It has now been three years since I resuscitated this set. Recall all of the original electrolytics except for a replaced 40uFd axial lead unit are original. Most of the paper dielcetric capacitors were changed. I left a few units which were bypassed by resistors less than 100Kohm. And a few resistors which I found drifted when it affected performance. I then decided to run the set regularly and report from time to time on it's performance over the years. It is well past 1500 hours.
The set has developed two problems:
1. The original KRK2 tuner fine tuning has a bad back lash which make it difficult to fine tune. I believe it has to do with the slop in the shafte which I have to address. The second is a horizontal sync issue which causes the horiztal oscilaator phase to shift briefly and jump back. It is very momemtary and occurs rarely. Have no idea what it may be and keeping an eye on it.
But this set has been incredibly reliable and delivers a very good picture for a set which is 76 years old. Here are a few snapshots from over the air CHCH TV channel 11 this morning.
