I am looking forward to this project! I bought my first piece of audio in 1975 when I was in the Navy and had my first real spending money. 168 bucks every two weeks! Since then I bought many amps and receivers from many companies but I never Marantz because the specs never "measured up to the others". My son gave me a 2220b about 10 years ago and I kicked myself. I never knew what I was missing. I love the Marantz sound!
I'm glad you're rebuilding this amp. When we sold the Marantz 1060 in our stores, back in the 1970's, it had an unacceptably high failure rate. I don't remember exactly why. It was built like a tank though. That anodized champaign gold faceplate was killer. 😃
I not 100% sure, but I think it's the resistors behind the heatsinks failing from temps. This causes a chain reaction of other parts failing too. I've seen this concerning the 1060 on Audiokarma a few times. There may be other reasons. I'm replacing these resistors with high quality/temp military spec resistors made by Vishay. I may replace every resistor on the power amplifier board with high quality replacements.

I was listening to my 2245 last night. After the restore, it really is special.
