Hi,
Thank you all for your time and reading my post. I just recently purchased a Philco 37-650 that I'm working to restore. I picked up this hobby mostly because I enjoy woodworking and wanted to restore the cabinet. My first radio I restored a few months ago was a Zenith 8s463. I wasnt sure about restoring the chassis because I never worked with electronics but after receiving a quote for $1700 to recap I decided to give it a try. The chassis was a success and I also installed an MP3 jack. With that I'm starting to enjoy the electronic part over woodworking.
This is all a learning experience for me as I've been trying to read and pickup as much knowledge as I can. I joined this forum because I have some questions regarding this chassis as I have had 2 ECAPS ( c59, 10mfd) explode on me. I'm reaching out for any help to see where I'm going wrong.
All 3 ECAPS (C59,C59A,C57) I have connecting to a terminal strip rather that repacking. All three negatives are being tied together to the bias resistor and the CT. The positive ends of the C57 & C59A I have going to the B+ of the field coil. C59 (which keeps exploding) I have going to chassis ground. I'm still trying to understand positive going to ground. I believe I'm following the print but the results disagrees. In addition I'm noticing the detector, RF & IF tubes are not lighting. The radio wasnt working when I bought it. When I first powered up there was no sound. Could anyone validate my wiring for these 3 ECAPS specifically C59 positive going to ground.
Thank you all again.
