Yes, I've been enjoying cryo'd 6N1Ps I got from Chazz for probably a year now.  For digital, this is the way to go for me.  Now for analog tape, I like me some 6922s in the EL34 Monoblocks.

For reference: I was using a Mullard GZ32 rectifier, Mullard (Blackburn) EL84’s, Amprex 6922 PQ white label.

That's a pretty nice lineup!

Boead, my impression was similar on the bass - not so much lighter, but more like he stepped back a bit behind the band (or was buried deeper in the mix). On the plus side, imaging has improved and is more "locked" in and not "floaty" I'm using a cryoed NOS Raytheon "Uniline" 5U4GB. [/quote]
Its been just a couple of CD’s and I’m not doing so well but in all fairness, I’ve been listening to my Select my way for along time and I’ve gotten use to it.
Rock benefits from the stock tubes, very lively!

I usually like my Jazz more laid back, but some instruments really do shine through. I may leave the SV83’s and 6N1P for a while but change the rectifier. Any suggestions or just grin and bear it?


I just went through my tube stash. Unlike others, I don’t keep a ton of stuff. I sell what I’m not using and don’t really want. About a year ago I sold off most of my tubes and just kept what I liked and what I though I might want. As well as lots of 'stock' tubes for gear I still have.

• Ruby 5U4G (one unused from Steve about 2 years ago and the other the original one that came with the Select with the bass notched out)
• RCA 5U4GB (orange lettering with black base, USA)
• RCA 5V4G ST bottle (sm.), very nice looking with black base, USA.
• RCA branded GZ32 made in Great Britain (R XXM1), sm. shoulder bottle.
• Valve Electronics CV593 (GZ32 March 1967)
• RCA 5U4G large ST bottle with black base, USA.

• 6922 – pair of Amprex PQ white label, USA.
• 6DJ8 – pair Amprex Bugle Boy, Holland (white)
• 6DJ8 – Mullard, Blackburn short grey plates (classic white)
• 6922 – Sovtek from a few years ago.
• 6N1P - Sovtek from Steve two years ago.

• EL84 – Mullard Blackburn classic 60’s. (I have 3 or 4 left)
• EL84 EiElites (early 1990’s, pre war. (have 7 left)
• SV83 – Svetlana, 2 are new from Steve two years ago. 4 are much older, two say 1994 on them.


I also have three awesome and rare Telefunken 12AX7’s, GAP/R computer long smooth plates. I really need to sell them.

I also have two Bugle Boy 12AX7’s with long ribbed grey plates which are maybe the best 12AX7 made in my opinion.

I have an untried cryoed 6n1p to swap with the BB 6dj8 I've grown accustomed to in my CS. Will report soon.

I don't have to tell you that's a loaded line  :)

Shipped direct from Russia, minimum order is $200.

Steve D., do you have these tubes?

[quote author=veryoldcat  link=1149544554/30#42 date=1149870752]Absolutely; the 6n15n-EB (the EB is seen as EV in the catalog, which is the same) are available from the Decware catalog. If I'm not mistaken, the newest CS amps ship with them.

If you can get a pair cryoed for comparison, the difference is completely surprising. Cryoed or uncryoed, it's an awesome tube, and is absolutely superior to the more lightly built "Svetlana" branded SV83 (imho).

When seeing these tubes listed on a couple of different websites, there is an order number difference between the 6n15n-EB and the 6n15n-EV. Steve lists only the EV on his site and as replacement tubes for his components. They are not one in the same from what I gather.
