Hello all, especially any Marantz guru's
I just finished re-capping a 1030 that I bought with one channel out. This is my first attempt at refurbishing an amp. It now turns on and sounds fantastic out of both channels.
I wanted to perform the settings described in the service menu, the first to set the bias on the amp board.
The service manual states I should have 7.5mv across R747 & 748. I only have .8mv across R748 and 51.7mv across R747. I haven't adjusted anything because something tells me there are problems.
Any input would be appreciated.
