Hi,
New here in the forums and I was hoping someone might be able to help me with an issue I'm having. I bought a 2266 head off a guy I know, like the amp so far but for whatever reason I cannot get the effects loop to operate. When I plug in my effects loop chain into the send/return and enable the loop the amp goes dead. I've tried a number of different ways right down to plugging in a single six inch cable between the send/return and any time you enable the loop the amp goes silent. I tried cleaning out the inputs, I even took the amp out of the chassis and took a look at the board to see if there was any obvious damage or loose solder connections, but I'm not an amp tech or electrical engineer so unless it's something obvious I'm not going to see it (I didn't see anything).
The guy I purchased the amp from never used the loop (doesn't use lots of effects and runs them all in front of the amp).
My question is: Is the VM's effects loop tube driven, and if so which tube operates it? If not then I guess I'm off to the dealer or tech to see what this will cost to fix.
Thanks!
