Having a look at the Philco 76
#4

Hi Jon and Jerry
I didn't take any pics but it really wasn't that exciting. Found a bad resistor, had drifted to double it original value. It was the det. plate load resistor was about a meg. Replaced the under the chassis caps one gave me a run for my money. Bottom line one of the terminals was used as a tie point not a connection to the actual cap. The way it was wired it didn't make any sense.Drove me nutz for a half hour or so trying to figure out what the heck that cap was in there doing! Found a parts pic location that listed it and then everything came together. Here's a pic of it from epay http://www.ebay.com/itm/Philco-Receiver-...462491bd01
So now it's all back together and working well but does have a little distortion in the audio. Need to check the tubes and in a hurry I replaced the det tube (24A) w/a 35 which may be the issue.
Tnx for your interest!
Terry

Hi OSanders, Look carefully at the band switch. Turn it slowly and "wiggle" it around the desired band. ...MrFixr55 — 12:33 AM

A pre war Hallicrafters, and an early one too, very nice! 1936 is pretty early for metal tubes too, which would explain ...Arran — 05:58 PM
