Adcom GFA545 II service manual

[kinku]

Hi ,
Anyone got a copy of GFA545 II amp service manual?
I am planning to take the amp to Europe and like to require the transformer primary if possible.
The power distribution board inside shows 220V and pins and primary has two sets of wires , so I am pretty sure it could be rewired.
Thanks.

It’s available on “manualslib.com” just register for a free account. It doesn’t show how to change the primary voltage though.
Google should help with a DMM to tell you which windings are which?

Try this - Adcom GFA545II Service Manual - no account required

It appears all you have todo is move the red wire from the 120v pin to the 220v pin.

It can be downloaded from the Hifiengine.com site:
Adcom GFA-545 - Manual - Stereo Power Amplifier - HiFi Engine


You do have to register there in order to download, but it is free and harmless.

I agree, didn’t see the numbers on the board - eyesight is not what it used to be.

Hi @kinku, so long to this thread but I recently acquired a GFA-545 II and living in Argentina (220v) I have the same concern. Did you o anyone else try this voltage change?
Thanks in advance!
