Hmm. I agree I think(lot of technical jargin in here for me). Had a bunch of amps blow up on me so. Know any good techs in the Chicagoland area that can do crazy custom poopie?I don't disagree with you from the standpoint of quality of PCB design, and yes a good tech can repair a PCB board unless it is really fried (a Traynor YBA 200 that I was asked to repair came to mind-burnt pretty bad from a tube failure). The key for me is getting the amp back in operation, and turret board design is easier for me to repair when I am away from home. And often times I find that PCB designs also take shortcuts on quality parts on the boards, but not always. And others do dumb things like mount the control pots, input jacks and more to the PCB board which can make disassembly a pain. My Ampeg V4 is PCB and there are no issues with its sound or reliability, but it was built right. Again, I won't own an amp that has the tube sockets and all this other stuff on the PCB.
