I have a Heart tubed CD6000 cd player. I like it okay but it lacks dynamics. It has Sovtek 6922 stock tubes and I'd like to try something else. I'm a noobie to tubes so what would y'all recommend to try and why? THX.
Follow Ups:
I like the RCA label 6922 with gold pins and marked in black ink on the box 'Made in Germany'. In a shootout of many 6922, 7308 & 6DJ8 tubes these were best.
The tubes are 1960s era Siemens and reported to use the extra fine .028 grid wire. At times these tubes fly under the radar price wise.
A few years ago, I bought a pair of Zaerix Gold Pin E88CC/6922's that sound very good. They are most likely East German or eastern block as they have flying saucer getters.That said, are inexpensive when found.

I forgot I had a pair of Audio Research labeled 6DJ8's made in West Germany in 1983. I'm auditioning them right now and 1st impressions are excellent.

Damn, the Audio Research tubes are keepers! My guess AEG Telefunkens.

Thanks for the info Can anyone point me to a tube that wwould be an upgrade from the sovtek that would cost $100 or less for a pair. A source for such a pair?
put in some reflector 6h23n-eb, and it will sound beautiful!
where can i buy these?
If you like the sound of someone blowing their nose in the background, then keep the Sovtek 6922 tube. I am sure it works well in guitar amps, where a certain amount of distortion is always welcome.
I agree with all posts here regarding the current production JJ Tesla 6922. As a matter of fact, its low microphonics (when compared to the previous production samples) and its dynamics lead me to believe that it is a completely re-designed tube.
You can still get a hold of some good NOS 6DJ8s. I like the RCAs. There is also the mercurial Jan Phillips 6922. Any of these (JJ, Phillips, NOS 6dJ8s) are miles ahead of the Sovteks.
All the best,
Vic
P.S. I am on staff at Pacific Valve. Take my comments for what they worth
RCA never made 6DJ8 tubes. Most RCA 6DJ8/ECC88 or E88CC label types could be from any source.
As you probably know, RCA sourced alot of 6DJ8s from Siemens and Philips.I've got a couple pairs of Siemens Munich made 6DJ8s with RCA label and "Made in West Germany" on the RCA box. They also sound very nice in my Heart CD6000.
When I was using a Bottlehead Foreplay 3 tube linestage driving a solid state amp I preferred the Siemens. With my current solid state linestage driving the same amp I prefer the warmer Amperex/Philips.
Yup, RCA did source ECC88/E88CC/E188CC tubes from just about everywhere. You can see RCA label Sylvania, Amperex US or Holland made, Siemens, Matsushita etc. etc. Search for the text "RCA label" in the search box in the tube pic lib link below for some examples.
Some fake RCA's that are Russian tubes with recently printed RCA label have started to appear on ebay, Europe and far eastern markets. You can easily spot these from typical Russian saucer shaped solid getter, and solid mica spacers and the printing style.
Thanks for the link. I've had your site bookmarked for quite some time ;)
I have found it to be very helpful and truely appreciate your efforts...
BTW, those RCA labled Siemens with the orange label in the ECC88 section are exactly what I was refering to above.

In my Njoe Tjoeb cd player, based on the Heart. ECC88 Siemens and Valvos for starters. E188CC if you want to move up. Some of the older ones from the early '60s are as good as any CCa. And, of course, CCa tubes by those companies. You can't go wrong. They'll make your music infinitely more realistic.
I have the same CDP. Have done a lot of tube rolling and keep returning to 1960s Amperex 6922 or 6DJ8. They are warm, dynamic and are nice on vocals. I'll have to try the JJs mentioned below...
I have an AH! Njoe Tjoeb CDP that also uses 6922's in the output stage. I'm currently running a pair of 60's Toshiba 6DJ8's that I've been told sound very similar to Amperex Bugle Boys. They're alot cheaper than the BB's when you can find 'em. The JJ 6922's sound almost identical to the Toshiba's in my CD player and are a good choice for new production 6922's, IMO.
I too have a AH Tjoeb CDP. It came to me with Gold Pin NOS Siemens E288CC's. I've tried several different 6DJ9 types of tubes in her, all NOS, including a pair of 6922 PQ's. Simply put, the Siemens have the biggest soundstage, are neutral and will last longer than any current production 6922 IMHO.

I agree with Pat on the JJs. Unlike their crummy octal tubes, their E88CC has gotten better and better. My last batch was really excellent.
If you want a warmer tone use the JJs, they're now a good tube. For more neutral tone and the lowest noise use the EH.
I agree with you. I have always found a good place for them, and their predecessors made by Tesla. Mainly in amps. Nice tone, a bit on the warm side and limited HF extension.
I'll take a pass on the EH's though in sources and pre-amps. Quiet yes, but neutral? Tonally maybe. I tried them in my SP10II and a Raysonic CDP and I found the mids thru upper bass thick and muddy when playing discs with very well recorded complex music, mainly classical. Not as apparent with jazz and pop, just sounds like it could be a recording with a better low end. I haven't tried them in amps yet. FWIW. For reference, in newer production 6dj8/6922's I usually find I like the EI's in most sources and pre-amps (wish they would work in my SP10!).
"I agree with you. I have always found a good place for them,"
Until the last year or so I had a good place for them too - the trash bin. The quality was horrible. But the last 3-4 batches in a row have been excellent and improving.
"I'll take a pass on the EH's though in sources and pre-amps. Quiet yes, but neutral? Tonally maybe."
That's what I mean.

That's not a widely held view, FYI. In fact it's the first time I've ever heard anything at all like that. If the EH aren't liked, it's usually from lack of "warmth" as compared to the European tubes. I thank you for the feedback though, I'll file it away for future reference for sure...
That's why it's always good to remember your ears/system/room/etc. are the final judge of any component in your system.
BTW, you of course know that Ei is shut down, and there is no new Ei stuff being made. And the old stock 6DJ8 family is drying up VERY quickly. So it's good to have the two current tubes - both are FAR better than the old Sovtek.
"I'll file it away for future reference for sure....". I bet in the same place you put the old JJ's. :-)Jim, FWIW, I bought the EH's based in large part on your prior indorsements here. You just can't please everybody, even with free information! I'd hoped they might be a fit for the SP10. Another Asylum member used them in his SP10 and liked them. Obviously there is a lot of stuff between the tubes and the sound, and between the sources and the tubes. Perhaps I've just become too acclamated to the sound of 6h23's and old Sovteks from the same time period in the '10' and compensated for this elsewhere.
Yeh, too bad about the demise of EI. Fortunately I've got plenty (for me) and the supply of quality new production 6922's/6dj8's is really thin. Like my hair, and its not going to get better, I think.
Chuck,
"I'll file it away for future reference for sure....". I bet in the same place you put the old JJ's. :-)
Oh no! I'm a feedback sucking pig! The more opinions I can amass the better prepared I am for future questions. I wasn't kidding!
"Perhaps I've just become too acclamated to the sound of 6h23's and old Sovteks from the same time period in the '10' and compensated for this elsewhere."
Just so you know - the 6922 EH IS a 6H23...
either Sovteks nor 6h23's, but if the new 6H23's and the 6922 EH's sound alike I'll take your word for it. To my ears my 25+ year old 6h23's and Sovteks of the same vintage sound remarkable alike (some even say they are the same tube, its that close to my ears but I like to 'think the Sovteks are just a 'tad' cooler) but when I sub'd in the new EH's in my SP10 and they sounded nothing like the old tubes I had in it, nor the Sovteks that my 6h23's replaced. I had them all on hand for A/B'ing. Now you've got me curious. I'm going to set up appointments with my ear Dr and if nothing shows up, I next consult with my head Dr. :-) Maybe I'm just a nut!
