Audio Gain Potentiometer - R2

Audio Gain Potentiometer R2 R2 - $5.00

A high quality 100 K Ohm linear resistance potentiometer. 1/8" diameter x 3/4" long round brass shaft. 270 degree rotation. Includes mounting hardware.


Power Adapter - A1

A1 Power supply A1 - $5.00

(NOTE - If you are ordering the SSQ-2F V3.21, then do NOT order this power adapter - it will not work with the SSQ-2F V3.21.)

An AC to DC adapter block ("Wall-Wart") suitable for testing or powering the SSQ-2F. Input is 120 VAC 60 Hz, 6 watts. Output is rated at 15 VDC @ 150 mA, unfiltered.

This adapter plugs into a standard North American mains power outlet. The DC output cord is 6 feet long and it is terminated with a standard 2.5 mm phone plug, positive tip.

You will need to cut off the power plug and fit the end of the power cord to the SSQ-2F power connector.

My tests show that the actual output voltage drops to the minimum required to operate the SSQ-2F at duty cycles above 70%. This is a current limited power supply. This means that should an accidental short circuit occur, the SSQ-2F should not be damaged.

The bad news is that this is NOT a filtered power supply. In order to use this power supply with the SSQ-2F, you must add a 4700 uF 25 Volt electrolytic filter capacitor across the DC output of the power supply. The good news is that it is cheap.

Washer-1 & Washer-2, Insulated Shoulder Washers for TO-220 Devices

TO-220 Clamp Washers Washer-1- $0.75, Washer-2 - $0.25

Washer-2 left side of picture; Washer-1 right side of picture. (Transistors NOT included with washers.)

These shoulder washers are used to securely mount TO-220 devices to a heat sink. They provide mechanical clamping for the TO-220 device and electrical insulation for the mounting hardware. Please note that the use of either PAD-1 or PAD-4 is also required for proper insulation of the TO-220 device from the heat sink.

Washer-1 is a general purpose, high temperature, shoulder washer suitable for mounting TO-220 devices to heat sinks. Washer-1 is made from 40% glass filled Polyphenylene Sulfide PPS. It is rated for continuous operation at temperatures of up to 260 C / 500 F. It is rectangular in shape to provide excellent clamping action.

Washer-2 is a general purpose, moderate temperature, round shoulder washer suitable for mounting TO-220 devices to heat sinks. It is the type that you usually see in computer power supplies and audio amplifiers. Washer-2 is made from 30% glass fiber reinforced Nylon 6/6 GF-30. It is rated for continuous operation at temperatures up to 170 C / 355 F.

Both of these washers have the insulating tube for the mounting screw slightly longer than the thickness of the TO-220 device metal tab. That allows the insulating tube of the washer to extend inside of a drilled through hole in the heat sink to keep the TO-220 device mounting screw centered in the mounting hole. If you require that the tube of the washer is flush with the back side of the TO-220 device, then you simply insert the washer through the TO-220 device tab and use a razor blade or a sharp knife to trim off the excess part of the tube.

This thermal pad allows heat to pass from the IRF730 to the heat sink. This heat sink should not be used with the STW20NK50Z in the PA1. Please use PAD-4 for the STW20NK50Z. If desired, PAD-4 may also be used with the IRF730 for better thermal performance.




PA1 Rife Plasma Tube Amplifier With HS2 Heat Sink

PA1-HS2 Combination - $175.00

This setup saves the researcher valuable time in obtaining and fitting the correct heat sink to the PA1 amplifier.

The powerful but quiet cooling fan operates on 12 volts DC, and allows the PA1 to be operated at full power for as long as the researcher desires. The PA1 itself is fitted with the Quick Change option, so the MOSFET may be easily and rapidly replaced should the need arise - no soldering is required - just two screwdrivers, small wire cutters and possibly a pair of common pliers.

The HS2 features a rugged solid aluminum core, measuring 30 x 30 x 28 mm, which provides a massive 25.5 cc of heat absorbing mass to rapidly remove the heat from the PA1. To dissipate the heat into the air stream provided by the cooling fan, a total of 108 fins with a surface area of 812 cm^2 or 125 in^2 extend into the airflow. The HS2 maintains a safe operating environment for the MOSFET on the PA1, ensuring stable operating conditions and high efficiency.

Please download and read the instruction manual for the PA1 before ordering.


PA1 Rife Plasma Tube Amplifier Without Heat Sink

PA-1 - Assembled & Tested, $75.00

The PA1 is a high-frequency switch-mode power supply designed to convert DC power into semi-square wave pulses of energy at 3.1 MHz at a power level sufficient to drive the largest plasma tube.

The PA1 has been designed so that its output matches a standard 50-ohm load impedance, making it possible to connect the output of the PA1 to a conventional antenna tuner or to the 3.1 MHz link coil coupler. Due to the design of the PA1, the output signal from the PA1 is of the same high quality the output from the SSQ-2F v3.10.

The PA1 is designed to be driven by the SSQ-2F v3.10. The PA1 increases the power output of the SSQ-2F v3.10 to a power level of between 300 to 500 Watts peak power. When using modulation duty cycles of between 0 to 100%, the PA1 will produce at least 300 Watts peak or continuous power output. For modulation duty cycles of between 1 to 50%, the PA1 can produce up to 500 Watts peak power output. These power levels are sufficient to operate even the largest plasma tubes.

The PA1 comes complete with a high-efficiency Bergquist thermal pad to go between the STW20NK50Z MOSFET output transistor and the heat sink. A rubber pressure pad is required when clamping the STW20NK50Z against the heat sink. This pressure pad is included with the PA1. The STW20NK50Z may also be mounter against the heat sink by using a machine screw passing through the mounting hole of the STW20NK50Z. The thermal pad MUST be installed between the STW20NK50Z and the heat sink, or the high voltage power supply will be short-circuited directly to earth.

The STW20NK50Z output transistor connected to the circuit board of the PA1 with a 3-pin screw clamping connector. This attachment method allows you to simply loosen three screws and replace the STW20NK50Z in a matter of seconds. No soldering is required.

The PA1 must be mounted on a substantial heat sink for proper operation.

To connect a plasma tube to the PA1 requires the use of either a commercial antenna tuner or the 3.1 MHz link coil coupler.

This is a double sided board, with plated through holes and 0.05" wide, 3 ounce tin plated copper traces for reliability and durability during assembly. This board is solder mask coated to protect the circuit traces. It is fully silk-screened for ease of component placement identification during assembly. Four mounting holes are provided for mounting the completed circuit board.

PA2 Rife Plasma Tube Amplifier With HS2 Heat Sink

PA2-HS2 Combination - $225.00

The PA2 plasma tube amplifier may be driven by the SSQ-2F v1.41 or later models of the GB-4000 frequency generator.

The PA2 plasma tube amplifier is designed to be driven by a SSQ-2F v1.41 processor when the SSQ-2F is set to output a TTL level (0 to +5 volt,) 3.1 MHz square wave square-wave duty-cycle modulated carrier. The PA2 may be driven by any other frequency generator that is capable of outputting a similar TTL carrier signal.

The PA2 may also be driven by any frequency generator (such as later models of the GB-4000) that outputs a 3.1 MHz sine wave carrier that is square-wave duty-cycle modulated, with a peak-to-peak amplitude of 4.5 to 5.5 volts.

The powerful but quiet cooling fan mounted on the rugged HS2 heat sink allows the PA1 to be operated at full power for as long as the researcher desires. A separate power supply for the cooling fan is not needed, because the PA2 provides power for the fan.

The PA1 is fitted with the Quick Change option, so the power amplifier MOSFET may be easily and rapidly replaced should the need arise - no soldering is required.

Two power supplies are required to operate the PA2, one supply of +20 volts for the logic circuitry and cooling fan, and another of between +50 to +175 volts, depending on the type of plasma tube being used. Please refer to the operating manual

for full technical details.

LC Series - 3.1 MHz Link Coupler for Plasma Tubes

LC31P - LC31S - LC31OST - LC31TCBA - Complete Coupler Assembly, $85.00

The LC series of plasma tube couplers have been designed to work with the SSQ-2F v3.10, the SSQ-2F v3.21, and the PA1 or PA2 amplifiers. Using an LC coupler allows you to to efficiently feed RF power to your plasma tube while preserving the excellent signal quality of the SSQ-2F system.

The LC31 coupler system has been designed to perform properly with plasma tubes manufactured by Bill Cheb, such as the SSQ-PT, SSQ-ST, SSQ-BAT, the 5" and 8" Phanotron tubes, and the 7" x 18 mm Quartz Ar/He and Ne/Ar tubes. Other makes and models of plasma tubes may be used with these LC31 couplers, however it may be necessary to change the value of the series link capacitor or the coaxial tuning capacitor, however it should not be necessary to modify the LC31 coil assembly itself.

Starting with a tubular PVC coil form, a heavy-enamel insulated 18 gauge copper wire secondary coil is wound directly on the PVC coil form. This coil will connect to your plasma tube. A primary winding of 14 gauge PVC insulated wire is then wound over the center of the secondary coil. The primary coil accepts the RF power from the SSQ-2F v3.10 or the PA1 or PA2. Two high-quality Mica capacitors allow tuning of the primary winding for maximum power transfer. A high voltage coaxial capacitor is then connected across the terminals of the secondary coil. This capacitor tunes the secondary coil to match your plasma tube. Should you decide to use a different plasma tube, the coaxial tuning capacitor may be easily removed and replaced with a different one. Screw terminal connector blocks are used for all electrical connections to the LC coupler. There are no wires to solder.

Using the LC31P or the LC31S is easy. Connect one end of a 23 foot / 7 meter length of 50 ohm coaxial cable to the RF OUT connection on the SSQ-2F v3.10, the PA1, the PA2 or the PA3. Connect the other end of the coaxial cable to the input terminals of the LC coupler assembly. Connect two insulated wires from the output terminals of the LC coupler to the electrodes of your plasma tube. That's it! Now, power up your system. No tuning is required.

If you are using a Bill Cheb 5" or 8" Phanotron tube, the Cheb 48 mm x 20" (2" x 20") SSQ-ST tube or the Cheb 7" x 18 mm Quartz tube with the ARGON/HELIUM gas mixture, then you should purchase the model LC31P coupler assembly which comes with the model TCP (blue) coaxial capacitor installed.

If you are using a Bill Cheb SSQ-PT 1" x 16" tube, or the Cheb 7" x 18 mm Quartz tube with the NEON/HELIUM gas mixture, then you should purchase the model LC31S coupler assembly which comes with the model TCS (green) coaxial capacitor installed.

If you are using a Bill Cheb SSQ-BAT 3" x 33" tube, you should purchase the model LC31TCBA coupler assembly which comes with the model TCBA (yellow) coaxial capacitor installed. If you are using a Bill Cheb Original 2" x 26" Super Tube, you should purchase the model LC31OST coupler assembly which comes with the model TCR (red) coaxial capacitor installed. NOTE - The 2" "Original Super Tube" is a special order tube, and is not generally recommended for use with the SSQ-2F system due to the high drive power required.

If you already have an LC31 coupler system and you want to use your LC31 coupler with a different plasma tube, then you will need to order the correct TC Series coaxial capacitor for the LC31 coupler to be able to work with the new tube. In order to properly adjust the LC31 coupler for use the other tube, you simply switch to the new TC coaxial capacitor and, if necessary, move the jumper on the input terminal block on the LC31 coupler to a different position. The time required to make the change is approximately 1 minute.

Other makes and models of plasma tubes may be used with these LC31 couplers, however it may be necessary to change the value of the series link capacitor or the coaxial tuning capacitor, however it should not be necessary to modify the LC31 coil assembly itself.

Please note that in order to allow the plasma tube to be placed at some distance away from the computer and control electronics, the LC coupler system has been designed to operate with a 23 foot / 7 meter length of 50 ohm coaxial cable between the output of the SSQ-2F v3.10 or SSQ-2F v3.21 or the PA1 or the PA2 and the input of the LC31 coupler system. Please note that using connecting cables of less than 20 feet / 6 meters in length, will require an adjustment to the LC coupler. Such use is not recommended.

CAUTION: the use of connecting cables shorter than 23 feet / 7 meters in length may cause damage to the SSQ-2F v3.10 or the PA1. If the LC coupler is not adjusted to compensate for the shorter cable length.

Please refer to the instruction manual for further details.

Please select plasma tube to be used:

For those researchers who wish to assemble their own custom plasma tube couplers, we offer the LC 31 coil assembly.

This is our standard LC coupler coil assembly, but supplied without the coaxial tuning capacitor. It does include the two Mica link-tuning capacitors. These may be removed and replaced with different capacitors for tuning if desired. The standard operating frequency of the LC31 coil assembly is 2.5 to 3.5 MHz.




TC series Coaxial Tuning Capacitors for the LC3

TCP - TCS - TCR - TCBA - Coaxial tuning capacitors for the LC3, $20.00 each.

Your LC31 coupler system can operate with these Bill Cheb tubes by using the appropriate tuning capacitor: The 8" Phanotron tube, the SSQ-PT or the SSQ-ST plasma tubes, or the Original Cheb Super Tube.

All you need to do is change the TC coaxial tuning capacitor on the LC coupling assembly and change one jumper on the input terminal block of the LC coupler.

If you are ordering a complete LC31 coupler, then you do not need to order one of these capacitors unless you want to be able to use it with a different plasma tube. The LC31 couplers are furnished with the proper coaxial tuning capacitor.

Excessive heat is the most common cause of Plasma tube failure. This type of damage will typically result in contamination of the gas mixture inside the tube, causing an unwanted color shift in the discharge and/or poor performance. The process of ionizing the gas causes the glass wall of the tube directly under the electrodes to become very hot. Using ordinary bare copper or aluminum electrodes may result in damage to the tube wall due to overheating if high powers are used or if the electrode is too small for the power level being used. Untreated copper or aluminum electrodes do not effectively remove excess heat from the plasma tube.
