Hello boogie heads,
After having had my Mark V for nearly 3 years now, I decided to swap out all power amp and pre amp tubes with OEM 6L6's and 12AX7's and the rectifier tube (overhaul of all tubes)
After the swap, i hooked everything back up together (I have a Boss GT 10 sitting in the FX loop of the amp), I switched the amplifier on - gave the tubes time to warm up and tried testing it with a few chords...............I got a clean channel sound in all three amp channels ...
baffled...I tried a few more things before I switched to hard bypass and fx loop off....now all I heard was a wall of silence on all three channels.
flabbergasted, I pulled the GT 10 out of the loop altogether and the final chain was Guitar->Amp->Speaker cab....absolute silence again ...
I swapped the 5U4GB tube with the old one and still no sound in the straight simple signal chain...
I need some help/guidance from y'all - should I be looking swapping out V1 instead? I don't understand how I got only clean sounds on all three channels (with the GT 10 processor in the FX loop) with all the right gain settings. I've doubled checked my wiring and perhaps it's my lack of understanding of the pre-amp chain..unsure what the issue was?
I've called Mesa and left them a voice mail - hopefully will hear back in the next couple of days.
Meanwhlie - any inputs are highly appreciated...
Tnx \m/
