I have a trio of small (22w and below) vintage amps, as well as an Excelsior... and a 6g2 clone on order that will likely end up with NOS tubes. I’m currently practicing with two groups on the verge of gigging, something I’m looking to do as much a possible. I’ve been reading up, and feel the need to protect my tools/investments. As it stands now, I’m looking at ordering a Furman AC 215-A power conditioner and either the Amp Maniac or the Brownie. As best I can tell, they’re basically the same thing. Can anyone tell me whether one may be a better choice and, if so, why? Please don’t respond with “just get a variac” ... I don’t want something that could damage the amp if I have a brain fart. I’m prone to those.
