I picked up this radio at a local flea market. It was in fair shape and dirty. The radio smells like cigarette smoke as it heats up. Below you can see what the top side looks like.


I changed all electrolytic and film capacitors. Below is the underside before I change capaitors.



Here is a photo after: 



The only issue this radio had was an open 33k ohm resistor coming off the meter adjust pot. The symptoms were the meter seeing a constant 7 volts across it and a lower screen voltage on the first IF amplifier. Once the resistor was replaced the voltage went away and the screen grid voltage went back to normal. 

Cleaned up face.

  2. I do not have a list. I simply changed all electrolytic capacitors. I was not able to find much service information.
