38-116 died the 3rd time! Guidance Please?
#38

Well, after running through chokes/transformers, resistors etc. I never realized how many parts in there tested just fine! Depressing.Icon_sad Going through the caps in the area suggested by Brenda was a real PIA. They had previously been replaced with the total removal of the old cans. I hate that. So we went through, removing the old and installing the new. Probing around I saw a little spark down underneath everything. A little more probing and moving of wires and the radio now is working just fine! Apparently a couple wires were intermittently shorting out.
In this searching it also looks as though I missed adding one cap on the restuff. This was cap 123A. I jumpered one in there and it made no difference. Should I put one back in there?
Radio has played nicely for 4 hours and the transformer is not even warm.
On the low voltage the transformer was warm to the touch after 5 minutes. Also the 6L6s you couldn't pull out by hand after a couple of minutes, now no problem.Icon_biggrin
At 115V AC I'm getting 300V on the screens of the 6L6s, just like I should.
Thanks all of you for your patience. After this I may give up on radios. Regards to the two that stuck with me on the last two deaths. Couldn't have done it without your help. Now if my friend will just pick it up before it undergoes the next death.
