We are the designers of the POWER PLUG line of attenuators. The BEST attenuators on the planet for the money.  We offer our series of instructional DVDs, TUBE AMPS 101, on vintage tube amp repair. Aimed at beginners and those with some experience, we use REAL vintage amps so you can HEAR the symptoms and SEE the repairs.    Of course we buy and sell vintage gear too! We have been participants of the Dallas Guitar show and others since 1994 and introduced our product line at Summer NAMM in Nashville in 2013.
