Check first for some loose connections or weak solder joint. Similar thing happened with my SFC-1, where i had to take cover off, and while amp on tried to locate loose connection. I found one and since then i am OK. However, Sonic Frontiers is almost as helpful as Golden Tube, except i hurried and ordered schematics for my amp while the company is still 'pretending' to exist. Good Luck!
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
