Spectral DMA 200

@jalbertwebsterjr  : Here you can rea part of the Spectral topology design.

I always admired the Spectral designs and had opportunity to listen to it 3-4 times and are excelent and normally the owners don't let it go their units:

Spectral Audio DMA-180 High-Current Reference Amplifier

Btw, maybe you need to test your unit loaded and not " empty ".

Dear @jalbertwebsterjr  : All the Spectral models have a unique Spectral topology where between other things the unit is tunned at each single stage in the whole circuit boards.

So with out schematics is a truly hard task try to fix it and been Spectral rthe only one to fix it then you are in Spectla hands. Even if you touch the boards ( at any place ) and you send to Spectral they will refuse to fix it.

Btw, transformers could be a hum source and the Spectral ones were custom made.

Dear @jalbertwebsterjr  : " know where to source an owners manual/spec sheet? "

You started the thread with that statement with out disclosing your real " agenda ":

""  looking for a wiring diagram for this amp. ""

You are in Agon since last december and you have only one post tha's in this thread.

I don't know what you want to do but does not exist a " wiring diagram " for an amp, exist schematics of its circuit boards that I don't think you can have for a Spectral unit.

What moves you to ask for that " wiring diagram "? what do you want to do with?

You can have some kind of advise if you disclose exactly what you are trying to find out .

Regards and enjoy the MUSIC NOT DISTORTIONS,
