I've got a great deal locally on 2 Adcom GFA545's. Only caveat is that they were purchased by a serviceman overseas (Europe I believe) and he had them converted from 220V to 110V by an electronic shop when he returned stateside. Anything I need to worry about? Long out of warranty and currently set up to be listened to.

    If they work fine with 120 then they are fine. The transformers are capable of being wired for both voltages. No problem. BTW nice amps.

    Please. Please contact me a ben62670 @ yahoo.com. Make sure to include who you are, and you are from Polk so I don't delete your email. Also I am now physically unable to work on any projects. If you need help let these guys know. There are many people who will help if you let them know where you are.
    Thanks
    Ben

    Thanks! I'm working on a dedicated 2ch room and figured this would be a good start. Can't believe some of the finds on CL! NAD 1600 and these amps for less than a c-note apiece!

    The only thing that needs to be changed is the power transformer.

    Same performance, 99.9% of the time.

    Fuses should also be changed to the current level associated with 120V instead of 220V. If this hasn't been done already, contact Adcom to find out what they are.

    Wouldn't a 4 amp fuse at 240 be the same as an 8 amp fuse at 120?

    Yes.

    240 must be from Britain or Australia.Most others atleast in Europe are 220-230.
