Sitting around my abode in various places is three identical Sony TC-K61 2-head cassette decks. Don't ask me why, I love 'em. But each one has issues. Two of them have faults in the REC/PB amplifier board. Some bad component somewhere. And one of those has a flaky transport too. The third unit is the one with the broken transport that I repaired (turns out, only to a degree) here (http://www.tapeheads.net/showthread.php?t=4091). But it has flawless REC/PB PCB system.
So, little doubt where this thread is going.
After counting solder joints and evaluating whether it'd be easier to swap one PCB or swap one transport, I decided to swap the one good transport section into the deck with the one good REC/PB PCB system....
Nicely, even on a deck of 1980-vintage, Sony used many push-connectors instead of all-solder joints. So the task was not as hard as believed at first. I had some anxiety to work off after watching PennState play the worst football of a long time against Iowa tonight. They clearly didn't deserve to be No.5. Anyway, the brain transplant is done..... pics tomorrow. But at least for now I power it up and there's no magic blue smoke..... *yes*
