Hello, Just wondering if someone can help me out. I have been reading up about the VR relay mod that prevents the amp from automatically switching into standby mode when the voltage drops (see this thread for more information) I own a VR that has not had the mod made, and with the less than reliable power supplies that most venues have, I am interested in making the modification as soon as possible. However, are there any downsides? Does this built in protection also help look after the amp when there is a power surge, and by effectively removing this feature am I putting the tubes / other components at risk? Many thanks in advance for your help, Chris.
