I think it'd be kinda cool to have a toob speaker amp, but I'm too lazy (and time-challenged) to build one up from scratch. Are there, by any chance, kits out there? I'm not looking for nickel- cored transformers with solid silver windings, genuine paper caps rolled on the thighs of virgins, toobs dipped in LN2, and all that crap: I'm just looking for something that'll give the audio quality of a mid-range amplified speaker set, in a cabinet that shows off the fact that it all uses ancient technology to get the job done. Suggestions welcome. Is toob a brand name? What sort of amps does toob make? Someone should start a retro amplifier company and call it "Toob". Really. Someone who loves vacuum tube amps, but doesn't suffer much from audiophoolery. Someone came out with a book a year or two ago, where he came up with some different name for "tube", almost as if a new hip name would make tubes trendy again. Vacuum-mode field effect transistor? Since you asked, I checked, and it was "Thermatrons". This is a book published within the past five years and written by someone named Grayson Evans. Michael I had a prof that referred to them as "GlassFETs". -- Tim Wescott Control system and signal processing consulting www.wescottdesign.com |
