[Hallicrafters] Hallicrafters S53 A IF transformers and parts

[John King]

Thanks, Joe. When I get around to the S53A, I have switches and pots to clean as well as caps to change. No Hum eminating from audio.  I hope it is not the IF cans unless I can find replacement parts. I used to just change the cans in the old "all American fives". Will keep you informed. 73, John, K5PGW

John, that sure sounds like silver-mica disease in your IF transformers. You may be able to repair those IF transformers. Here's a link to an article on the repair process:  http://ppinyot.com/if_transformers.htm  You can download the manual for the S-53A for free: http://bama.edebris.com/manuals/hallicra/s53a/

Good luck.

I just acquired a very nice looking S 53 A receiver that makes noise similar to the static type noise that the All American Five BC radios made when the IF transformers needed changing back in the 1960s. I also suspect a dirty/defective  sensitivity and/or audio gain control. Volume is very low but there is no AC hum. I
