Tubes Asylum Questions about tubes and gear that glows. FAQ |
|
I have aquired a st70 amp that keeps blowing fuses, even after all the points to checks as told to me by the excellent folks on here.
I find that the previous owner ran a wire from the #19 (driver board point) and has it going to a 470uf 400volt cap to ground instead of to lug #3 on the filter cap. Was this some type of know mod from days gone by or just a bass ackwards attempt at a repair? Or is a section of the cap hooped? The value of the cap seems high!!
Would anyone happen to have a copy or scan of the assembly pictorial for the st70 amp? I have the troubleshooting manual, but I would like pictorial as Im new to tubes.
