Classic gear from yesteryear; vintage audio standing the test of time.

RE: McIntosh MA6100 repairs

Thanks, Michael. Interesting that the schematic doesn't point to those as close tolerance parts.

In this case, there was no DC offset problem with either channel. I thought the repair was finished. Then, I noticed that the heatsink on the non-repaired channel ran hotter than the channel I'd repaired. I was getting ready to run some further tests suggested by another McIntosh technician to check for problems when that channel suddenly blew both 5A fuses at the same time, just sitting there on the bench.
