Title: AA1164 princeton pops twice
Post by: goldstache on December 03, 2021, 11:24:51 am
Servicing an aa1164 Princeton reverb and it pops through speaker 2 times every time it’s turned on.
New power filters/droppers, tubes, etc.


Pops at 10ma draw and 20ma draw like clockwork, as tubes start to conduct.


Then all is fine.


Does it hot and cold cycled.


Any ideas???
