So, three weeks ago I powered up my Dr Z MAZ Jr 212 (non-reverb) and blew the 1/2 amp fuse. I replaced the fuse and changed out the power tubes. I played the amp again for about 20 mins, put it on standby and when I turned it back on it blew the 1/2 amp fuse again. At this point I ordered a new rectifier and just installed it today, but upon power up the amp immediately blew the 2 amp fuse. I'm not sure what to do, and any advice is appreciated! thanks!
