This one turned into a marathon! Nasty faults which took a while to fix
but I got there eventually. Folow me step by step as I diagnose and fix a succession of faults on this amp caused by an arcing EL84 output vakve.

One last thing and I'll stop! Actually my favorite el84 tube for the blues junior or most other el84 amplifiers is the electro-harmonix el84.

I have to totally agree with Thomas. Your explanations throughout the video are what other repair videos are lacking. Great job Stuart ! I subscribed. Keep the amp repair vids coming

Hi Stuart,When you want to read voltage on brown and blue output transformer leads, Youll have to unplug the speaker (load) on the amp output trransformer). Then youll be able to read volage with your multimeter. (2017 blues junior circuit pcb). Thanks for sharing all those videos.

I enjoy all of your videos but this one is in my top 3. I so wanted to reach thru and disconnect that blue OT wire that was getting in your way lol.

Overall a good video with reasonable explanations. What I do not like is your fear to take out the main board and fix everything the best way possible .... without doing this you get from one additional issue to the next.

Great stuff. I purchased new, a USA manufactured BJ in1999 (Rev 2 1995 green board) and have been unable to find any information regarding a parallel resistor except mentioned here. As I understand R37.33k and R31.22k (resistors per the schematic) make the voltage divider in this board model so the 33k ohm R37 would receive the parallel resistor. What would be a reasonable resistor value to parallel across R37 to reduce the bias?
