Members albano1973 Posted March 4, 2014 Members Share Posted March 4, 2014 I play out a lot. I use a Vox AC30 but I also use a Fender Bassman 100-Watt from the 70's, it's an older silverface Recently it blew a fuse When I replaced the fuse, it blew a fuse again I know I got to take it in, but do you think they're gonna tell me "You need to change the tubes" or they're gonna to tell me I need a huge costly repair where it would almostbe better to just buy another fender bassman from the 70's like on ebay? I really like it's tone Link to comment Share on other sites More sharing options...
Members WRGKMC Posted March 4, 2014 Members Share Posted March 4, 2014 Likely bad power tubes or possibly shorted power caps. If you been running it on a higher impedance cab the bassmans have a tendency to blow the grid resistors. Hopefully thats all it is. They are cheap to replace. 470 ohm 1 watt resistors. The tubes go south running with the wrong impennce then the grid resistors blow taking out the fuse. I did this to may bassman many times as a ked before I figured out what was going on.If the caps went bad it may have blown a power transformer but lets hope for the best. A transformer is about $100~150 which still isnt bad. You'll need a matching quad set of power tubes though. Link to comment Share on other sites More sharing options...
