Soon I'll be able to play my freshly rebuilt Pioneer PL-12D deck
through the Goodmans!


Nearly there, but not quite.

I fitted all the new caps, with the exception of the two C69s,
which are too difficult to get at without a complete dismantling
of the board's wires etc. Two caps unchanged, out of 20 or more.
If I ultimately have to change them, then I will do so.
Replaced the damaged resistor.
Checked that the cassette player would play through both channels,
Balance and Volume controls worked, etc.
Re-assembled everything, including outer casing. Repeated cassette
player check.
Brought FM aerial down to workbench from usual location, plugged
into socket.
Selected FM, no sound except for a very faint cross-talk, when at
full volume, from the cassette player. No FM, though. The Tuning
lights appear to respond, so the failure is somewhere after them.
Oh dear. Back to the diagram and interior of the Module 80. When I
get more time.
Grrr.

One day.......


I fixed that ok, it was just a broken wire. But I then dragged the
record deck down, and plugged that in, and there is only one channel
getting through the system. More debugging.

That was the track you broke earlier.



It's OK! This problem was a dirty socket at the back of the unit. Like
everything else, it's been in storage for 30-odd years, and after a few
in-out actions of the plug, it seems to have cleaned up the connectors.
Now it all works !!!!!!!!!


And with all new caps, for at least another 30 years.

Now to make a raspberry pi based MP3 player/internet radio and shoehorn
it in...

I made a whole 'music centre' for me mum and put it inside an old oak
coffer (17th century) to it could all come out again. Still got the coffer..
