Possibly a failing tube or a leaky cap. Correct, it’s unrelated to the power amp (power tubes/valves, transformers, etc.) Proper troubleshooting will narrow down the area responsible for the noise, then it can be appropriately repaired. 1 Quote Link to comment Share on other sites More sharing options...
