Members kakiking1 Posted August 20, 2021 Members Share Posted August 20, 2021 Hello, I've recently bought a used Bugera amplifier. After I plugged it in, it turned out that the LED at the front keeps flashing with more or less one second intervals. At the back, there is also a LED which signals the need to change tubes. I replaced both tubes for the ELECTRO-HARMONIX EL84 model. But after all that, nothing changed. What can I do to fix this? I have an electronics degree so I can measure or replace any electronic elements. Unfortunately, I don't specialise in tube amplifiers which is why I'm asking for your help. Thanks Quote Link to comment Share on other sites More sharing options...
