Hello guys! I thank you for every help I got from you! Here you can see my finished Pioneer!

A video will also follow ;)

Finally it’s working again! Thanks to all! There is only one little problem remaining… since the head mechanism works again there is this problem…. I’m a bit confused.

First of all thanks for the advice from the last post!

After some recapping, speed adjustment and cleaning, this is how it sounds! You can hear the mechanism is working again. But the tape head doesn’t move. How can I fix this?

Update on my Pioneer HR-100
I’ve identified the following issues so far:
The right channel has quite a bit of hiss/noise. The left channel also has some noise, but noticeably less.

Many capacitors on the amp unit seem to be bad.

The indicator lamps for tracks 1–4 are not working.

The Pioneer is not switching tracks properly, so it seems to be stuck on one program.

The unit runs too fast.

The power transistor on the speed adjustment unit is dead.

I also suspect that some transistors on the amp board are failing, which is probably causing the hiss/noise.

Other than that, the deck actually plays surprisingly well.
The belts still look decent, but I’ll replace them anyway.
The capacitors in the amp section will be replaced with Nichicon UKLs.
The power supply unit will also be rebuilt using Panasonic capacitors.
Do you guys have any additional tips for this restoration?
Also, what’s the best approach for servicing the head/block mechanism so the track changing works properly again? I assume old hardened grease is causing the mechanism to stick.
Thanks in advance!

Edit: X means no recap.

I will give updates to this beast!
