Sony TA-1120A re-cap is now complete!

I had previously completed all the capacitors on the preamp/power amp/power supply boards last week. This resolved some noise issues on this unit.

I replaced the five large chassis mount capacitors tonight and last night.

One of those big caps has a super corroded terminal; guessing it has some kind of internal issue as the unit runs massively cooler after replacement.

All the removed capacitors. One of the large chassis mount capacitors has a corroded terminal, which may indicate internal degradation. That one was also running very hot.
