I got a series tube reg ps thats two high 250volt. I've got 12at7 au7 ax7 I got 6gk5 6ak5 417a which I've never tried d3a e180f two much gain and current. I got nice octal and loctals. If I fudged up a separate filament supply I could try cm3.I got lots of pentodes even el84 triode with the ll1630 winding parallel I bit much gain. I want good band width so I want to run loop fb just a little. maybe 12b4 is the go if I parallel. Anyone, I need some encouragement. prefer to stay with 9pin less chassis work. The 7pin would be a bit messy too. Never tried at7 because there not linear but maybe thick tubby but tight sound is what Iam after.. I got ss E choke 250volt supply too Iam running remote blue alps motor winder and one of those shiney china selectors that take the circuit board untested. Hope their ok. Just want to try a tube I haven't used for most fun. I chose idh because I want it supper quiet compact and reliable. I want good phase come to like good phase of the f7 driving fullrange. Something I might miss might only full range currently. au7 would be novelty for me. I haven't tried those in 20years like all the common ones.
