6922 tube recommendations
A couple of years ago I purchased a Musical Fidelity x-can headphone amp. I followed MF's directions and left the thing on all the time, and eventually the tube burnt out. I bought a cheap replacement and it sounded like crap. Specically it had way too much noise to be enjoyable at moderate volumns. I basically haven't used the amp since then.
Given that my wife has been busting my chops for playing my music too loud at nights I was thinking of bringing this amp back into the rotation. However, I need to replace the tube before even considering it. Does anyone have a recommendation for a good 6922 tube? tried searching the forums w/o much luck.
thanks

I've used a pair of Russian "Rocket" logo tubes in my preamp for a while now. I got them from Upscale Audio, but you can actually pick them up for about 1/4 of the UA price on e-bay (I recently picked up some back-ups). Just make sure they are the true "Rocket" logo on them. The Russian logo's determine the manufacturing plant over in Russia and for some reason the one's with the rocket on them sound best and don't go microphonic as easily. You need to research the Russian tube factory logo's on-line to identify the proper factory name (Voskhod, Kaluga). http://www.ominous-valve.com/russtube.html Enjoy |
I just bought some Platinum grade Amperex 7308 for my preamp from Kevin @ Upscale and VERY please with the transaction and tubes. Ordered Sat and delivered Wed. Brendan @ tubeworld is a good source. His prices are on the high side but all legitimate top quality stuff. I've also had very good luck with Chris Johnson @PCX. Reasonable price with helpful advice. |
Those $35 cryo'ed 6H23 tubes are a steal. It's only that the supply is greater than the demand right now since not too many people know of them. Soon when word gets out and the few ( <100 ) out there are gone, they're gonna re-sell for hundreds. Even if you don't like them, keep them and sell them for double that in 1 year. PS: I'm not the guy selling them :-) |
I agree with Sidssp that a lot of so called NOS tubes are really junk noisy garbage. That is why you really need to buy from a reliable dealer. If your a gambling man and spend less up front but then separating the wheat from the chaffe then you can take your chances on the big auction site. Sometimes you win sometimes you lose, please be good and don't sell the losers. |
I replaced the older Amperex Nos tubes in my preamp with JJ 6922 tubes and it sounds great with strong bass, transparent midrange and good highs. I also saved myself a few hundred dollars by not going with Nos tubes again. The eight JJ 6922's cost me about a hundred dollars; Nos tubes would have cost at least $400 and more likely around $600. |
Sballs, Glad you're happy with Joe's Tube Tore. It is a nice starting place. But consider that it doesn't include any new production tubes which have varying tonal qualities and, if noise is your only real issue, that is still obtainable from some manufacturers. Quality NOS 6922's and 6DJ8's are really expensive, especially when you order some tested for low noise. If you specified what tubes you have now and how you view their tone, and what tone you would like, you just might get some specific and helpful responses. FWIW. |
Sballs, I suggest that you try Joe's Tube Lore as a good place to start. (It does not address your particular piece of equipment, but it does give a good solid base to begin your research from.) Joe's Tube Lore @ Audio Asylum Scroll about half way down the page to see where his review of the 6922's begin. Good Luck in your search!!!! |
