Hello everyone! So today I fired up my Vibro Champ and after a few seconds, it blew the fuse. I replaced it with another one, pulled the tubes and turned it back on. The jewel stayed lit and the new fuse didn’t blow. As I replaced the tubes one by one, all tubes had power except the 6v6 power tube. I had a known to be good tube I tried and it was dead. So, no power to the power tube socket. It’s sure looking like tech time, but what do you all think it could be? Thanks in advance.
