I bought a Marantz 2220b for an upgrade project a few weeks ago. Installed new caps on the power supply, tone board, and main amp board and replaced the large 6800uf 63v filter caps with 10000uf 80v caps (their actual value reads around 9000uf). I screwed up and had the polarity reversed on the cap for the left channel and cooked it. I replaced it but now the main 2amp fuse is blowing after about 20 seconds. I checked the output transistors and they check out good. Any insight would be appreciated.
