I like most Electrohome sets but the guys who designed this thing must have been Limeys. It's probably one of the worst radios I've had to work on in terms of design, deep chassis (for 1948 ), narrow from back to front, terminal strips mounted bellow the tube sockets on the inside of the back apron, weird routing of resistors and capacitor leads just to ground them to the chassis, and just for fun the mounted the output transformer under the chassis right bellow the power transformer. I only have an area of about 2-1/2'' x 2-1/2'' to access the bottom of the 6SA7 tube socket, which is made worse by the fact that Dominion Electrohome used some of the worst octal tube sockets known to man, even compared to other wafer sockets.
I've already broken off two of the terminals from the 6SA7 tube socket thanks to the awkward angles I have to work with, such that I'm thinking of putting a new socket in rather then trying to repair it again. The antenna coil got hit by lightening an replaced with a ferrite bar antenna, which never would have worked, so I had to find another coil. The speaker cables and the power cord are rock hard and cracking. Most of the resistors were either badly drifted or completely open. This set clearly had a high number of hours on it and was nearly run into the ground, if it had not belonged to this fellow's father I would have told him to scrap it by now. The Rogers Ten-60 wasn't this bad, and it had hand wired circuit boards connected to rubber wires!!!

Sounds like a real job to do that one 
I've restored a couple "deep chassis" 1930's RCA sets that were nightmares. The 140 was one that comes to mind. Hard to get to anything in that set.

The resistor is a 2.2 Meg, it was the last one I hadn't replaced. The broadcast is coming in after replacing it.osanders0311 — 09:09 PM |
