HEATHKIT SB-200: I have for sale a Heathkit SB-200 amplifier that I would call a project amp. No tubes are included. I have many pics with the cover off.
When plugged in it did have high voltage and that's as far as the testing went.
I have an HL-2200 so I don't need this one. I prefer local pickup and I am located in central Wisconsin

FS: OM Power OM4000A: Selling my OM4000A as solid state amps better suite my operating style.
The OM4000A is just back from OM Power's U.S. service center, and has had two new tubes matched by OM Power installed. It is in excellent condition with now scratches or other issues. Inside, it is bright and shiny, and is a joy to look at.
To give you a sense of the overhead this amp has, into my Alpha 2000 dummy load, I measured the following with an LP-700 wattmeter:
160m 9.1 in/801 out 13 in/1299 out / 17.1 in / 19.5 out / 25.1 in / 3268 out
10m: 12.5 watts in/2012 watts out.
Included with the amp is the OM4000A remote control unit, which allows you to turn it on/off, put it in standby/online, and also displays the power. Additionally, there is an embroidered cover to keep it dust-free. The original box and packing materials are included also.
$6300 - get it before the tariffs kick in. An OM4001A+ (the successor to the OM4000A) is currently $10,999.99 DXE.
