TK16, (and
@Guidostrunk) you are correct! I don't 'need' ('need' is a funny word on tube forums) 6 of these tubes.
I liked the HiVac so much I bought more pairs way back when and I have too many other tubes as it is! (is that even POSSIBLE???)
That is, in part, why I decided to not buy the TP or MJ2, at least for now, and keep the modest hybrid tube amp I have and know what tube I can use.
Just more tubes to hunt down and lust after with new gear and you guys are a bad influence on any of us tube-a holics!
I am quite taken with the HV 12AU7's sound but don't really need 6 tubes. There has to be some other high amplification shiny object (6201 perhaps) that might get me excited.......................
