Crate Limo TX50D schematic

[feves]

Does anybody have a schematic for a Crate Limo model TX50D. I have a broken one. I got a few bits and pieces from Loud Tech. I have the Pwr Supply, Mic Input Board, and DSP Board but no main board. Also the docs I have say TX50a. Loud said that was all they had and they lost a lot of stuff from the SLM archive. Thanks in advance.

The service disc is rather spotty on this.

Here is a more complete file on the TX50a, see if it helps. Just what part are you working on?

The amp failed after the 15vdc wall wart was plugged into the 12vdc car adapter input. Amp would power up and make a few small pops and the LED would light brightly at first and then dim down to a faint glow. The amp would have no sound. I found that one of the opamps was bad when I tried it in a known good circuit. The others were fine. It was a 5534 that was bad. I didn't have another on hand so I replaced with TL082. Amp still does not work but now it oscillates when powered up. I suspect the power amp IC is bad as it's data sheet says it's max supply is 18vdc and the 15v wall wart puts out over 20vdc with no load. Thought I would check the schematic to see if it might be something else. Diodes on the main board look good.
Thanks for your help. Will post updates as I look into this one more tommorrow.

I pulled the power amp IC out and everything looks good the power LED changes from Red to Yellow instead of blinking red and I get signal on the scope all the way to the power amp IC pin 1. However, when I replaced the power amp IC it is still not working. Back to where it was. Any ideas?

I was VERY careful not to give it too much heat when I put it in.

The replacement is TDA1562QCD that I ordered from Digikey not sure the make.
The original is just TDA1562Q made by Phillips

Thanks,
