2002-01-11 by gsp2101center
Hi guys I'm usually only using my 2:90's A channel but yesterday i tried back the B channel : It wasn't working anymore ! I have followed Mesa's directives all the time i didn't use the B side : Volume to 0 and Presence at max... All the 8 valves are lit but i have no sound at all : no hum, no fffff, nothing ! Do you have an idea ? Is it a huge repair ? thanks a lot GSP2101Center
