Hey all, I recently completed a hybrid amp of sorts. It's a Princeton Reverb style amp with an added cold clipper gain stage and a 3 way switch a la Robrob. See link below for more info. https://robrobinette.com/How_the_Marshall_JCM800_Works.htm#Cold_Clipper Everything functions well and it sounds killer but I'm getting a loud pop when I use the switch. I know I'm changing the bias of a triode so maybe a pop is to be expected but I'd like to get rid of it if possible. Is there anything I can do to quiet it down or remove the popping noise? Thanks.
