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!

It sounds like there might be a leakage issue with the standby switch or another component in your TC15 after installing the VRM and Dumbleator. It's not typical for audible signals to pass through when the standby is engaged. You might not need to remove the standby switch resistor, but checking the installation and connections of the Drift Hunters and VRM.

A standby switch typically cuts the high voltage to the tubes in a tube amplifier while keeping the filaments heated. This prevents the amplifier from producing sound, as the tubes are not operating at full power. Therefore, when the standby switch is engaged, it should not allow a signal from any channel, including channel 1. fireboy and watergirl

Some signals may cross channels and cause interference to the audio channel. This can happen if the devices are not placed properly or there is a problem with the way they interact with each other. geometry dash

From my research, it appears that placing a 47K ohm 3W resistor across the standby switch benefits the valves when the amp remains in standby for long periods. However, I noticed this isn't mentioned in the VRM installation manual. Consequently, I've decided to remove mine. Stephen, feel free to correct me if I’m overlooking something!
