Ok. I've posted about this before, but haven't done anything yet, other than buy this old tube amp. The unit was pulled from a Zenith mono record player cabinet (circa 1956!). The guy I got it from re-capped it, replaced the weak tubes, and converted the ins and outs to 1/4" jacks. The amp is 15 watts. There is a 6J5 tube in the preamp stage, a 12AX7 (it says AF Amp-Phase Inverter in the specs...is this for the tone controls?), a 5y3gt rectifier tube, and a pair of 6v6gt for output tubes. First thing to do is replace the old two prong cord for a grounded cord! I'm thinking this can be used as a nice small guitar amp pretty much as is. I'd have to move a few things around to get it in a cabinet, but no biggie. The one thing I was wondering about was the possibility of using this as a mic pre. I know I don't want 15 watts going into my PC, so I was thinking the way to go was to use an attenuator to reduce the output. Today, I was reading about removing an output tube from a guitar amp to reduce the power for lower volume playing. I got to thinking, would it be possible to pull both output tubes and just use the preamp stage? This is my first exploration into tube electronics, and I haven't found any info regarding this idea yet. I know from reading in this forum that Kev would be one guy to talk to about this, so c'mon Kev, tell me what a stupid idea this is! If I pull both output tubes, what will happen? I have a schematic, but I'd have to scan it at work tomorrow to post it. Peace!
