[How to] restore my McIntosh MC-60

[batman]

Thanks Kent.

Tubes seems to be ok. I tried to swap tubes to see if the problem moves to the other amp. No go. So I am ruling out the tubes as the culprit.

Definitely, the amp(s) may need to be checked again.

Since I love the sonic signature of my MC-60s, these amps will be back in service as soon as I have it fixed. ...Again.

Cheers,
Levi

The amp is fixed. It was a bias problem.

I also replaced the lamp cord with a grounded plug.

Cheers,

McIntosh MC-60 restored

Hi All,

Talking about thread revival.

Many years have passed after the restoration job, my McIntosh MC-60s are still in service providing me with many hours of enjoyment.

This amp is a keeper that is for sure.

Thanks again to everyone for the help!

I see this thread is pretty old. Anyone still out there. I am just beginning my MC-60 restoration. I have schematics, but none of these have expected voltage readings. Can I get something more details. Hope you all are still around. Anyone in San Jose CA?

And I suggest you start a new thread as this will give you better exposure (vs 12 year old thread). I've restored two of these; one with and one without the PS choke.
