Hi guys so I just installed the vrm and dumbleator in my tc15 and everything sounds great but I noticed that there is still a very audible signal flowing through channel one while the standby switch is engaged. Is this normal? I didnt notice it before but I can't promise the signal wasn't there before the vrm.

Am I supposed to remove the standby switch resistor maybe?

Thanks in advance,

James

Same issue here - have VRM (but not Dumbleator). Did you resolve the problem?

After some reading it seems that having a 47K ohm 3W resistor across the standby switch is good for the valves when the amp is left in standby for an extended period (this is the simple explanation). And I noticed in the VRM install manual it is not shown. So I've now removed mine - Stephen, please chime in if I've missed something!
