If you look through the original ZMA development thread, started by Steve, you might find his impression of the EL34 in the ZMA.  And if not, it still can be a fun read.

I am currently running a quad set of PSvane El-34PH's in my ZMA.  They are $350 and worth every penny, in my opinion.   Now, these are based on the legendary Phillips Holland EL-34s of the past.  Those you simply cannot find and if you happen to get lucky, you are spending thousands for a quad set.  

Are these on par, I don't know.  They sound exceptional to me in the ZMA.  But your question is more type specific that make/model specific, so my opinion on this $350 set of EL-34s may not apply to other, less exotic versions of this tube type.

I just received a quad of RFT ( SIEMENS ) - NOS - EL 34 from a vendor in Germany.  I can't say they are matched as well as tubes I get elsewhere, but the magic of the ZMA allowed me to get the bias dead on at 50.

They are sweet. I think I like my 6P3S's a tad better for air and high clarity, but it is close. I'l run them for a few days and report back.

My curiosity in the el34 is the hazen mod and if there is noticeable in anyway compared to the kt66.

I cannot comment regarding the hazen mod, but I can say that there is a distinct difference between the RTF EL34's and the TAD KT66's.  The latter have a very strong bass and crisp highs whereas the EL'34's have a stronger midrange with more than adequate highs and bass.  So the EL34's are smoother and more amenable to vocals, piano and strings.

I have a quad of NOS RTF EL34's with the dimple on top that I am willing to sell.  I paid $250 and willing to sell to $225 pus shipping.

Yes Norm the air and high clarity I'm getting out of the 6P's with Tele inverter's and Edi's or my Mull's for inputs, has me in heaven with this aggregate tube compliment. RCA NOS 0A3's.

Stone:

I have exactly the same configuration except fo the stock OA3's.  I may order another set as backup.  I have the Psvane EL34's on order, but I doubt they will match the 6P3S's.

Norm,
The El-34PH's are great in their own right.  I wouldn't write them off so soon.  I have them in now, and have been listening to them this past week.  They are contenders.  I would say the EL-34 class of tubes in the ZMA, in general, is at a disadvantage.  But there is something about this PSvane set that has me scratching my head.  Definitely not one to be generically classified.  It is an outlier, in the most wonderful way.  Keep an open mind and you may be surprised.

I did not intend to be that dismissive, although after reading my post , I can see it could be read that way. I will certainly give them a good listening. Id be delighted to find current production power tubes. Plus, I paid good money for them!

Sitting here listening to Lee Ritenour Smoke and Mirrors on the PSvane EL-34PHs.  These tubes produce a really unique, incredible sound.  Different.  They are LUSH3. It is a silky, rich, and very exciting sound signature.  Much different than the 6Ps.  I wont say better or worse.  So different that I cannot rightfully declare a winner.  It is one of those situations where 5 out of 10 would pick the PSvanes while the other 5 would pick the 6Ps.  Both sets excel in their own right, but from different sides of town.  Classic East vs. West.  

The midrange beauty of the 6Ps is undeniable while the lushness and sexiness of the PSvanes has me doing a double take in a completely different direction.  

I believe this is a situation where you shouldnt choose.  These tubes will be in my repetoire from here on out and will go in and out depending on my mood.  

But, value matters.  There is a significant price differential between the two sets.  I think they are equal when it comes to the highs.  The 6Ps have the distinct advantage with the midgrange and the EL-34PHs have the edge when it come to bass volume and drive.  

That is about as objective and honest I can be when speaking of these tube sets.  I really dig them both and plan to keep a set of each in my tube library.

Where is a good place to get the Psvane EL34PHs?  I may have to try a quad.
