I removed the rectifier tube (JJ GZ-34 with 125 hours) and examined carefully didn't see anything burnt or bad, I replaced the 5 amp slow blow fuse removed all but the three 12BH7 tubes and powered the amp up, all three lit up so I went to the next step and installed the rectifier tube and two KT-88 (I had marked tube location so the two tubes went back to the exact left front & rear positions) I hooked up the speakers and turned the bias pots full CCW then powered up the amp, all tubes lit up until the time delay relay clicked and then the rectifier tube flashed again.
I removed all tubes, 5 amp slow blow fuse and examined all Capacitors & wiring, nothing smelled or looked burnt, at this time I did not check the values of the capacitors.
I replaced the 5 amp slow blow fuse, three 12BH7 tubes and powered up the amp, all three lit up fine and stayed on for over two minutes, next I installed a new spare JJ GZ-34 rectifier tube and installed the two right side KT-88 in the left positions and powered up with the same results, rectifier flashed after the time delay completed.
I did check my outlet and it measures 120.7 V
I have very basic electrical skills and am seeking help on what to check next?
I don't have anymore known Good rectifier tubes so I need to order and am wondering about going with a Weber WZ-68 but cant seem to locate where to buy one, is there anything I can check/verify with out the rectifier tube at this point?
I do want to mention that I choose to post on the forum rather than going directly to Bob not because I felt like I had to but rather to share with others like myself that want to learn while enjoying some awesome sounding amps.
Any help is greatly appreciated.
