PostSubject: Stewart Warner Needs to Live Again   2015-10-10, 5:02 pm

My wife bought a Stewart Warner 58 Highboy over 30 years ago before we were married.  We have no idea when it stopped working, because it wasn't working when she bought it.  Over the years we tried to find someone to repair it, but it's been difficult.  Since I retired, I thought I might learn how to fix it.  I picked up a book called " Antique Radio Restoration Guide" by David Johnson.  After reading a few chapters, I removed the chassis from the back of the radio and did some preliminary cleaning with a vacuum cleaner and paint brush.  I found a number of issues that need to be addressed.  The power cord was so badly frayed I ended up cutting it off.  There is a vacuum tube missing.  A fine wire was broken from the oscillator going to a condenser.  There are quite a few items on my check list, but if I address them one at a time hopefully it will live again.  Please look at the photos and help me decide how to proceed.  Any and all suggestions are welcome.  Thanks in advance.

You need to get the schematic, because it lists all the parts and their values.
You can find it at nostalgia air. The chassis is common to several models. 
How many tube sockets does it have?
The model you mentioned shows 11. In the schematic that is. 
But on your picture I only see 9?
Look for the chassis number and see if it is 105.

The radio was made in Canada, is a superheterodyne, the I.F. IS 177.5 KHz.
The tubes are 2-57, 2-56, 3-58, 1-27, 2-47, 1-80.
It has a push-pull audio. 
It was made in 1932-34

Cleaning is the best step first.
Then get the tools, and then the schematic.

That's great!  I really appreciate your input.
