Adcom GFA-555 Pro

jbanneck · 15th February 2004, 04:32 AM

Does anyone have the schmatic for the GFA-555 Pro model? I would like to make my GFA-555 into a balanced input and I know the Pro version is balanced.

I didn't think it would, but checked my 555II Service manual, and it doesn't have anything on balanced inputs, schematics or otherwise. If no one responds, look-up Adcom manuals on Ebay. There is a guy that is always selling the common ones. Email him, to see if has the "pro" one.

I have four of the balanced input boards that I have never used. I bought these over ten years ago from Adcom, and just never got around to installing them.
If you are interested, let me know, and we can work out a price, and shipping.
Unfortunately, I live in the UK, so things will be a bit more expensive to ship.
I think I paid something like $100 for each one.

Cheers
