Budgie problem

Postby jcastellano » Tue Aug 13, 2019 8:10 pm


I am a bit lost. My budgie was lended to a friend and a few days later he told me the preamp did not turn on. I looked at it and the fuse was open. I replaced it and now the budgie starts the LCD and the arduino and also responds to the remote but the 24 volts line do not come alive in the tube circuit. I mean that the two biasing leds are not lit. Can anyone guide me where to look?
