Hoping someone can help me solve this...

(have to start off by saying while not a complete newbe, might as well consider me one...)

I’m doing a re-cap/build of a Marantz 1060 for a friend. Had all the parts in, unit was operating beautifully!!!

When I was reassembling it - mounting transistors to heat sink, re-attaching the front and rear panels - something happened.

When I powered it up, it sounded awful. Can not for the life of me figure out what happened?

After much mucking about which caused resistor R739 to flame out, I am back at it.

It is running again, albeit noisy as heck. The noise is in headphone outlet as well as main speakers. The noise is “scuzzy”...

One thing I am curious of right off the bat is when checking RCA inputs (the centers) they are not showing an open circuit?

Please help as I really want to solve this and return the amp in working order to my friend.

Thank you!!!

Something is likely shorted to the case.
Have fun finding it since taking the boards out is going to clear the short..
