Hey, man. I was wondering some stuff about amp modding. Right now I'm playing a carvin belair, which is a 50 watt combo using EL84s. It's a good sounding amplifier. There are a few things I'd like to do with it, and I was wondering if you could suggest to me a possible way to. I'm not a novice at amp modding and electrical work, but I'm no expert. I've done a few things to the internals of this amp, so I'm familiar with some of the insides. As of now, the amp uses four EL84 power tubes to run at 50 watts. How difficult would it be to add a 3-way switch so I could take it from using four tubes to two tubes to one tube? I figure that this is probably a pretty complicated process, but I'd love some advice. Thanks!
