 POWERSUP - FOR SALE: SAMLEX SEC-1223 POWER SUPPLY 
- ESTATE SALE: Samlex SEC-1223 Switching Power Supply $100 shipped USPS Priority shipping in CONUS, Zelle preferred but PayPal also accepted. More pics available. Local pickup is fine, will eliminate shipping costs & also give you the opportunity to test it in my shack.
I'm assisting the family of David Alden (WK8F), Silent Key, in finding new homes for his cherished equipment. David was a dedicated ham for many years, loved the hobby, and I've known the family for many years. This power supply tests fine in my shack. More pics available on request. As with most previously owned equipment, the power supply is sold "as-is".

 RADIOHF - FS: 275V regulator 4 516F-2 and PM-2 PS
- 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.

- POWERSUP - 22 AMP 1-45 Volt!!! = 1kw power supplies
- Perfect for that LDMOS amp project or use as a bench supply. I have a number of them. (I also have 12 and 24 volt versions). My company bought another company and these were in their engineering closet. Brand new in box. 109-120 Volt input. I placed a 3 ohm resistor on one and at 15 Amps (675 watts) they didn't even flinch. My meter read 45.1 volts unloaded and 45.1 with the 3 ohm load. I don't have a resistor any smaller to load it more but this will give you an idea of their regulation. There is a screwdriver pot to set the voltage and another for current. I backed the voltage down to less than 1 Volt so if you replace them with regular pots they could make a very nice bench supply. I haven't tested the current adjustment so I don't know if they crowbar or drop the voltage to your set level. $90 firm each shipped in cont. USA. Brand new but sold as is due to the nature of electronics. Good check (shipped after clearing) or Postal MO okay. Save $10 if you pick up in CT. 73. KC1KWX
