1 2sc2290 driving 4 2sc 2879
`s and dual fans on top there should be a led on the front of the Amp that says "heat" on it that will light when the heat sink gets too hot, and will also open the relays until the amp cools down.
I think the 900 model had 1 or 2 large red power leads and a big bolt on the Back of the case for ground...
If it is the amp I am
thinking of a Guy named Steve built them here on the west coast, i think it is the same guy that built Pirate amps.....changed the name a few times.
Some had a MRF 455 driving 4 2290`s some had a 2290 driving 4 2sc2879`s and so on depending on the model. TX
800, La900 and a few smaller ones.
They were good amps IF you keep the dead key into the amp very low.
The heat sink is very small for a Amp with that transistor set up, that is why it has two fans and the heat protection built in.
The case is pop riveted on, and you have to be careful when drilling out the rivets so as to not damage the board or components that sit very close to the rivet holes, same thing when putting it back together, if the new rivets/screws are too big/long same damage.
Lots of cores used in that amp, wrapped around the power leads, big Teflon coated wire, there is a lot going on inside that amp in a very small package.
I have never seen a Drawing of the inside of that amp.
HITECK REDNECK asked the same question some time ago and no results.

There is another thread here also that shows some pictures of the inside of the Amp if you search around a bit.
Here are some Pictures of the 500 model built by the same guy.
Thanks to pede69 for the Pictures.
Good Luck in your Search.
