How different 45 tubes sound dependes a lot on the amp they are used in and the driver tube. I am using Don Allen's 45 amp that uses the 6bQ7 to drive TJ's. The sound is fantastic. I have tried many other 45's in this amp and while they all sounded good I like the TJ's best. In another amp it may be a different story. Though I have to admit I have tried a lot of other amps and tubes and have stayed with the combination I have.

I want to chime in, here, and agree entirely with the "how different ... depends" comment. My "45" is Jeff Korneff's. I've tried at least a dozen different "brands" of N.O.S. 45s -- although I've always questioned (read: been skeptical of) their ultimate manufacturer -- and I'm *very* hard pressed to be able to identify any real differences in sound quality of *any* sort between brands. (For that amp, incidentally, a change in rectifier tube will make *far* more of a difference in sound quality. Sorry, haven't rolled a whole lot of drivers.) The esteemed (and now retired?) Mr. Korneff even went so far as to tell me once that I probably wouldn't notice anything being awry with different brands of 45 in each channel! It's a circuit that is simply not "brand conscious." (That we all were! -- maybe there's a lesson there....)
Hi Jottow,Hear lots of good things of Don's amps and wondered if you've done any comparisons with say the DRD45.
I've got the Star chiefs and maybe would like to improve on them though very happy at the moment.
Do you think Don would accept an email from me.
Thanks for your contributions to the forum
You likely know I too am a Don Allen fan. Have his 45 amp and 300b amps. LOVE EM, no regrets what so ever!Don also feels the TJ 45/300b tubes are one of if not the best.
I was the guy who snaged the pair of AVVT 300bSL on agon (have a hunch there used though). Since my EML went south (started arcing) I wanted another pair. Currently using china 300b-98c tubes, hey they sound amazing! no lie In Don amps the china tubes really sing but I found the EMLs to sound good when they work..... Only picked the AVVT tubes up as they were the same cost of new TJs, figured Id expand my horizon on taste.
I found the RCA black plates to be my fav 6bk7 and 6bq7 make. Although Sylvania also makes a black plate 6bk7/bq that is "almost" identical in looks and sound.
Also use the RCA bk in my CD and pre. Only use the bq in my 45 where they sound best IMO.Im my 45 int amp I like the 6by5G rec tube the best. A little smoother than the 6ax5 Don shipped it with.
Have you bought his CD player yet? If not, wait no longer.
All the best
I am using Muller 6bq7's and will try the RCA's. I did buy Don's CD player and am amazed at the performance. It ran circles around my Esoteric 50S at a tenth of the price.
