Hopefully the Tenor amp is worth the trouble! If it is - then stock up on your tubes; but if it's not - look at building your own or purchasing a 845 SE.
As one of the above posters said, I would contact ex-Tenor Audio technician Stephane Vermette at www.cdfaudio.com. Stephane can provide matched output tubes which are critical in obtaining the highest performance from the OTL.
