Band-switched SS 500w amp on eBay, Homebrew - nice pics

Interesting Homebrew at: https://www.ebay.com/itm/3348880844...d=link&campid=5336136228&toolid=20001&mkevt=1

The base amplifier here is an “ST” DB-2933-54 test bed for it’s RF POWER amplifier using 2 x SD2933 N-Channel enhancement-mode lateral MOSFETs on which I’ve added a case, metering and switching. Although originally rated for 300-400 watts, it can be easily be driven well above that and with a slight increase in power supply voltage, can approach 600 plus watts.

For the life of me I cannot find that Item again.
The paragraph above was a cut & paste from the listing itself. Found it late last night browsing ads. It ws cheap <$200 and had switched inputs for each band. Homebrew but small and finished in blue/silver. Something I'd never seen before, Fla located I think.

Well MANY amps on Ebay get pulled. If they can be used on 11 meters for sure they get pulled. Depending on how the ad is worded hey get pulled unless they are stated ham amplifier and it helps to say not for CB.

Some hand from above reached down to adjust the market. Sounds about right. Internet held such promise in the early '90's.
