Type 45 Tubes for stereo amplifiers

I have a Dennis Had Inspire "Fire Bottle" amp and LP3.1 preamp, and the "Fire Bottle uses 45's.  I love my Emission Labs 45's.

RCA  coke bottle style 34's sound very good and are reasonably priced.

I have used them in  my 45 amp..

Sorry, misstyped. 45 not 34.

A little off the subject but has anyone had experience with KR Audio tubes?

I’ve got four Gold Lion KT88s, nearly new, in the C-J ART27 amp now and wondering if I would hear a difference with the KR Audio tubes.

A bit pricy at 1300 for the set.

Thanks

Great thread, thanks all.

I’m beginning my flea watt amp adventure starting with the 300b, followed by 45 and a 2a3 amps.  After verifying with the designer/manufacturer I’m fortunate my 100db speaker can handle the 45.
