"Cap Job" questions

Post by T Moore on Sun Feb 26, 2012 7:20 pm

First, I'm a newbee so please be patient. I've got an old EMUD Senior Rekord 60 from the early 60's. It is one of the old table top AM/FM/SW/Tape/Phono (all mono) units. It belonged to my dad who died in 1965 when I was 6 years old. I have found a very basic schematic for the unit online. The unit does power up and I do get some decent audio and quite a few AM and FM stations. I know the unit needs a cap job and that's the topic of my question. Is there a general rule of thumb that can applied to which capacitors need to be replaced in a capacitor replacement job? Any information would be appreciated.

The most important caps to replace are the electrolytics, followed closely by paper / wax caps. I don't recommend plugging it in until at least the electrolytics have been replaced. It may seem to work fine now, but 50 year old caps are a ticking time bomb. If they short out then you will have much bigger problems. Let us know if you have any questions about how to do this & post pictures.
