On the bad channel, what are all the TR's you replaced since we were last testing?

What's the voltage on R153 and both side of R139? R153=23.44 R139= 23.38 and 24.32 |

What happened to the minus voltage from Tr115? Test BEC of TR115.

Remove R139 and get voltages from both pads.

Remove R139 and get voltages from both pads. ok wierd, it started low on both sides and rose !! 12.3 and 18.4 but it fluctuates. Also when i first touch the pads it shows a number around 25 then drops to those unstable numbers, and when i tested +/- B lines they did the same thing , highe 25 then drop to those other numbers.

Also to add TR119 and TR120 are now not getting hot at all. they were before I removed R 139.
I think one is damaged for sure.

Well they affect both channels but change them anyways if you think they are bad. Something just isn't right here but your are getting different readings with these TR's then before.

Pull TR113 and TR117 and see if everything cools down and test the B+,- voltages and then test Pads of R139

ok B lines good and on either side we have -25 and + 24.4
And Tr119 and 120 are getting hot again .

The -25 and +24.4 was on the resistor pads?
