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.

RADIOHF - Knobs and more knobs: Hi all, Forgot to mention, looking for the 4 knobs found on the bottom of the Icom 7410, and most likely the same ones two of them for the Icom IC-738. These two knobs are just to the left of the VFO knob on the IC-738. The 4 knobs on the IC-7410 are below all of the buttons. Thanks.
