SAE X-10A Amplifier Schematic Needed

TiMan · 30th December 2009, 04:29 AM

Does anyone know where I can get a schematic for an SAE X-10A? It's an old Class-A amp.

I just noticed your request: I can send you a schematic for the x-25A. The schematics of all of the X series amplifiers are very similar. In fact, the schematic for the X-10A is very similar to that of the A-201. The X-10A has some schottky diodes added to keep the output stage transistors from turning off during operation.

Hi all, hey I recently picked up an X-25a, has bad cr14,15 in one channel, that is those Schottky diodes of which you speak. Did any of you guys ever have any luck tracking down a replacement for those you needed? Would love to hear of any possible replacement for these as it's all I need to get this guy running again and I'd really love to hear it thru my M-L's. Desperatly seeking diodes...Steve

Omit the diodes!
It's the stupidest idea in amplifier design I ever saw.

Hi Mr. Tico, please forgive me in advance but what might your qualifications be for you to be reengineer this amp? Also, when you say do away with 'em, do you just mean open up the circuit by removing them, or short across where they were? Please give me a bit more info than "silliest amp design I've ever seen". These amps sell for in excess of $3,000 when working all day long on ebay, so it must not be all that silly. Steve
