Looks like it runs 8ea of the PT9847 TRW pills in it on a push/pull. I sort of expected it'd be a power supplied version of the Metron MA1000B mobile amp (I own one) which indeed it appears to be...except for the finals. The MA1000B mobile amp has MRF455's in it which are Motorola transistors. I haven't fired it up yet but will here hopefully in the next week or so. I really need to locate the instruction manual or schematic to insure it's wired properly. I'm guessing the old guy had it wired for 230v which I have in the shack...but no telling how long ago this amp was run. I'm going to bring it up on my variac first just to be on the safe side.
It sure is a good looking old amp though...way ahead of it's time. Doesn't have 10m in it just 15-160m. I found a place online that sells the manuals for even this, but they want like $20 for it. None of my usual online sources have it listed, so I may have to cough up the cash for that manual. But if you guys know of a source I can download the manual I'd sure appreciate a PM with a link. I'm not much for solid state amplifiers in the shack, but what the heck...I figured it'd be something fun to try. It's not like I need it either but you never know. I've just not seen any of these on the used market in the past several years. So I said what the heck. Judging by what I'm finding online it should be an 800w amp, but really with the biasing I'd guess 600w. Which is perfectly fine. My tubers do quite a bit more but for a solid state not bad. Besides, it appears to be built with the same bullet proof layout as my MA1000B. Man that amp just has been a joy to own and fairly forgiving.
Anyway, I'll let you guys know how it goes. All my shack amps are tubers. In fact, I also picked up a pair of brand new in the box Eimac 3-500z's from looks like 1978 which preliminary testing shows they are good. Hopefully when I burn them in they won't be all gassy (story of my life LOL).
Whatcha' you guys think? Did I do okay?
