I have some KT150 for the Firebottle amp on the way; have cycled thru all of the other tube recs with no real improvement in woofer control.
Have a pair of red base RCA 5692 in the preamp now, which did in fact increase bass...but they also are very microphonic so the increase in bass came at a cost.
Any 6sn7 variants that anyone could recommend that would increase bass? Or any suggestions overall? Many thanks in advance.

No guarantee yet on longevity, but I just received a second quad (backup set) of TJ Full Music 6SN7s. They were supposed to all be backups to my Sylvania 6SN7GTs. The Sylvanias are put away now. Liking the TJs after more burn-in. They were making them for Sophia Electric before. Snagged another set before they are all gone. Time will tell.
