I will update this thread with details, might be useful for others having the same or similar issue.

It's a cute little set and worth fixing.
Probably is basically just working and needs to have solder joints reflowed extensively, pots/switches cleaned, and some bad electrolytics. The lytics can be tricky in sets from that era. Sometimes you will find one value or brand in a set that every one has gone bad, and other times it will be all of them. Usually, if it's just specific location caps, it's stuff that's close to heat sources. Anything near a big heat sink or power resistor or power transistor could be dried out and useless just from sitting there next to the heat
