Silvertone 7054

Post by frank1956 on Thu Jun 12, 2014 1:12 pm

Hello my name is Frank,
I just recently got interested in antique radios and restoring them. I picked up a Silvertone 7054 chassis number 101.808. I have the schematic for this model, but am still a newbie to this type work. I have looked at several article on antique radios and watch several you tube videos. I know the first thing is not to plug them in and to replace the Electrolytic capacitors first then replace all other capacitors.This is my first re-capping and need help with the Electrolytic. There are 3 (2) 40 MFD and (1) 20 MFD. They are inclosed in an aluminum can and I do not want to cut it open, but rather do them from the bottom of the chassis. The question I have is how do I determine which clip there are 3 of them is the 40 mfd and which is the 20 mfd, also how to I determine were the neg part of the electrolytic is to be attached?  confused Not sure how to post a picture

In your radio, the negatives are tied together and are connected to the on-off switch. As for the other terminals, there is usually a legend stamped on the side of the capacitor which corresponds to the symbols printed beside the terminals. Be sure to cut the old capacitor out of the circuit!

Thanks for the replay. I see what you are talking about, but only one wire to the on/off switch is connected to the negative side of the electrolytic case, the other is connected to pin #5 on the 35Y4 tube. So all negative leads from the Electrolytic would connect to the negative side for the on/off switch?

All three negative leads should be connected together & go to the switch where the old cap is now.

Thanks. Hopefully the New Electrolytic capacitors will be in shortly.
