Hi Tom,

Thanks for the info on the HO trans temp and B+ current. Yours seems to be running nice and cool. That gives me a good benchmark to shoot for. I just got back from a vacation and my freez spray has arrived, so I will try and find some time to look for temp drifting resistors this week to see if I can nail down the large shift in convergence at startup. The funny thing is that after half an hour of running, when the convergence has stabilized, I can turn the set off for 15 seconds or so and the convergence drift will re-occur. But it will re-stabilize in about 2 minutes.

John Folsom has told me that I should replace the flat green power resistors. John says that these type power resistors are known for being a problem. That is the next thing I will try.

Thanks again for the data on temp and voltage/current readings. I will post again as progress is being made.

Bob G.
