RCA portable insuffient B+ Boost

[hobgoblins]

I looked at the dual damper diode again and they do hot and they look like they are causing the high HO cathode current and the B+ boost problem also. What is the data on them. I have 1 with the code IOR D818 and 2 other ones with the code 010 7142 SCI.

Um.. are you saying they do run hot? If so, they are probably shot and will cause the very problem you are describing. Sorry i can't give further specs as it's been a lotta years and memory's a bit faded. I do remember that the dual diode was introduced because of the extremely high failure rate of the single. Testing the thing with an ohmeter did not reveal much, and the only real test was to sub in a new one.
