PS, Antique Electronics Supply has virtually anything and everything you might need in order to build an amp yourself, including soldering stations, resistors, transformers, speakers, etc. About the only thing they don't have are speaker cabinets. Easy enough to find or build. There's also MoJoTone, and ebay, etc. So, don't let 'not having the stuff' stop you!!
