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.; Listing #1736598 - Submitted on 07/18/25 by Callsign K6HM, Modified on 08/29/25 - IP: 75-37-192-218.lightspeed.lsatca.sbcglobal.net; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend

Icom PS-20, Speaker/ 20 amp Power Suppl: Icom PS-20, Speaker and 20 amp Power Supply FS:
-
The Icom IC-PS20 is an external power supply
that also includes a nice speaker. The PS-20
delivers up to 20 amps at 50% duty cycle (10
mins on and 10 mins off). This power supply
will switch on automatically when the rigs
power switch is pressed.
-
Cosmetically, this supply matches many Icom
rigs. It has a special 2 pin plug on it that
matches some rigs, but also has an adapter
to the more standard 6 pin molex plug.
-
This one works 100% as it should, and looks
very close to new. No defects.
-
Buy it for $125 plus shipping from Florida.
Pickup up near Ocala is also great.
-
Thanks. 73,
