Philco 37-690 with a 38-690 Chassis??
#2

Just take you time and be very careful to make sure you replace all the caps and out of tolerance resistors carefull so they are right the first time. 

If all the parts are there to start with, the radio should play like new wen you are done. 

The lamp sockets are important too if like the 38 690 as the insulation rots. Ron has a fix for that o this site. 

I used this procedure on my 38 690 four years ago and it is still playing strong every day.  I had only fixed small radios up to that point. Taking eack chassis step by step.
