 POWERSUP - FS: 275V regulator 4 516F-2 and PM-2 PS 
- Due to old 1956 design of 516F-2, or PM-2 power supply for Collins KWM-2 (A) or 32S series transmitters runs on 125V AC power Voltage, the 516F-2 supply should deliver 275V Low Volt becomes 330V Plus minus during receive mode of KWM-2(A), vacuum tubes get 330V which will shorten life of tubes and cause extreme hot temperatures affect other parts. KWM-2(A)and 32S series transmitter get lot of heat problems. I have a solution to keep the LV to exactly 275V either transmit or receive mode.Using 500V MOSFET and series of Zener regulators,LV is now tightly regulated which helps keep the VFO with no drift and no audio hum as it works as ripple filter.The board is 22mm x 30 mm by size, made with SMD components and can be fit to the sidewall of power supply. Price is $40 plus $6 for USPS. two or more it has to be shipped by priority, price is $13.check to my QRZ.com address.Other output V,150V or 250V or 300V if needed.

- RADIOANQ - FS Kenwood TS-830s
- Selling my Kenwood TS-830s hybrid radio. This radio has CW Filter Yk-88C and YG-455-C1 for narrow capabilities. I switched the jumper to just YK-88C because the YG Filter is too narrow. I repainted the top case of the radio, and it appears the previous owner replaced the power cord but drilled a new hole. Im asking $425 shipped via PayPal, and if interested I can provide videos of the radio working. No microphone included, but will also include an original owners manual.
