Run a search on audioasylum tube forum. I recall a thread on this a while ago and it did not appear to be a major repair for a technician experienced with tubes. There used to be a useful listbot email thread going, but that is no more.
Golden Tube SE40 : pwr led & input tubes kaput
I was wondering if any other Golden Tube SE40 owners have had this same problem and if you have had any luck getting it repaired. When you power up the amp the six power tubes light up but the two input tubes and the power led don't. Obviously a power supply problem of some sort. With Golden Tube out of business its impossible to get schematics. Any help with this problem would be appreciated. Maybe a tech in the Tampa,St Pete Fl area. I hate to get stuck with a 45lb doorstop. Thanks
