Hi there! I'm new here and didn't know where else to look for help.
I own a Diezel VH4S (yes, stereo) since 2001, and it's still a great amp! It was delivered with 6L6 but I changed very soon to EL34 and had no problem for many years. Being curious, I recently tested those TAD Pen Tone Class A converters with EL84 tubes (I believe they're similar to those yellow jackets many people use), for what I always thought is that my amp has two separated power amps as A and B channel (maybe that was wrong, though...). Well I like that other sound too, and the opportunity to blend the EL34 and EL84 sounds with the stereo master is great!
Now the problem:
I recently wanted to play the EL84 in Power amp section A through all 4 speakers of my Diezel 4x12 cab. Remembering the golden rule "never play a tube amp without speakers!", I thought it would be alright if I took out the fuses (1+2) of the EL34 tubes in power amp section B. Seemed to work for the moment, I just wondered that the tube fault led on tube 2 was lit. When after that I wanted to use my stereo setup again, power amp section B was absolutely silent, and no bluish glow inside the EL34 anymore. Seems like taking out the fuses doesn't turn the VH4S into a 50W VH4 . Section A is still fine, no tube fault led is lit.
Does anybody have an idea what this might be, or if it is a severe damage? I'm a bit worried right now...
Thanks for any replies!
