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.

RADIOHF - For Sale: TS-930 Front Panels
- I have two (2) front face plates for the Kenwood TS-930 HF Transceiver. I purchased them a project 930 some time ago. The project is long gone so now it's time to let these front panels go as well. One panel has all the components installed along with the wiring and some of the associated connectors located behind the panel. The other faceplate is the faceplate alone, no controls, no connectors,..., just the face plate. BOTH front panels are in excellent condition. Clear lettering, no marks, no dents or dings, etc. Sale is final due to scammers and parts swappers. I have additional photos for those who are interested. Asking $85 for both face plates and components, shipped to the continental U.S.
