Hi Greg,

LOL Smiley

I did not expect a road toll for this thread. Wink

I can recommend getting a pair of Siemens PCC88.
E.g. EBAY item 221331998591
They are value for money tubes.

The Telefunken PCC88s currently sold by Upscale Audio are actually Siemens made PCC88s.
They have the same internal structure.
Even though they are newer tubes with silver shields, they are pretty good with linear extension at both ends of the audio spectrum.
The mids are also slightly warm in a good way.
They are also cheaper if sold under the Siemens brand name.

Regards,
LS

I PM'd a guy over at the hoffman site that sells tubes. He had these for sale. Any opinions on these and the prices for them?They aren't 7Dj8's but probably shouldn't let that stop me if they are good candidates.

6DJ8/6922/7308 and 7DJ8s will all work in a 6922 circuit. I have the following available right now, prices include shipping and insurance in the U.S. All tested on my B&K 747B tester and passed life/shorts/grid emissions; sections match to 10% or better, all test as NOS.

Pair of Siemens Munich (German Philips factory) branded for CBS 6DJ8s; "X" seams, etched datecodes, single support rod "O" halo getter, early 60s production/oldest I have in stock, these sound really good, probably the most balanced sounding I have at this time... $70

Pair of Philips Herleen Holland plant (1 branded Amperex, 1 branded GE) 6DJ8s; single suport rod "O" halo getter, "X" seams, etched datecodes, GE bottom tuck flap torn off and taped over by previous owner, another great sounding pair (a little less costly due to different branding - some folks are very picky about that, it really makes no difference as Philips didn't hold back better quality tubes for Amperex or any other brand that bought/sold them). These are a touch more lively sounding compared to the Siemens made tubes, not zippy bright, just a slightly more alive sounding midrange. $65

Pair of Mullard Blackburn plant (branded Amperex) 6DJ8s; "A" frame support rods with "flying saucer/solid dimpled disc" getter (some folks swear by these - the "A" frame is supposed to be more rigid/less susceptible to vibration, boxes have loose/ripped/repaired flaps, mid 70s production. $60

Thanks guys for all your great advice.  Greg

Greg,

I have a pair of Siemens early 60's 6DJ8s and they are really good tubes. Extended and linear, open, delicate detail, and transparent. Not sure how these relate in construction, but mine have single support hallow getters and are labeled Haltron. Also have a pair of Mullard labelled 6DJ8 A-frames with the same construction described, not sure the year, but a very nice tube also. Warmer than the Siemens, but with a nice open midrange, and pleasant but subtle euphonic thing going.

Not sure about the Heerlin tubes. I have liked bugle boys which are constructed similarly, but only now and then...they have a particular upper mid bump that can be good or not depending. Don't know if these would be the same either. Bugle Boys with D getters are different and quite interesting. Also the Heerlin made A-frames have an upper mid bump that is sometimes nice, and perhaps just right in the right setting, but I like the Mullards better here.

I think these are quite good prices for these NOS testing tubes.... good inputs of the open mid variety.

The Telefunken PCC88s I have, I got from tubemonger, and they are different than te ones LS describes from Upscale. Mine have the more typical chrome plate that the getter rises off of, and therefore I can't comment on the sound of the upscale ones or the like Siemens, but LS has done a lot of good homework for us all!

So LS's right up on the Lorenz PCC88 tube in the CSP preamp sort of has me intrigued, to point that I impulsively order them from an Ebay seller in Lithuania.  He has over 100 transactions w/ 100% positive reviews.  I paid $100 total for a matched pair shipped.   Hopefully I did alright,  I couldn't find any reviews on them in a Torii MK3 but since LS like them so much in the CSP I'm hoping they do just as well in my amp.  Also  the listing didn't mention if they were 2 or 3 mica.  Have to see I guess.

If these don't blow me away, then I'm gonna get some of the other ones you all were so nice to recommend.

Please feel free to let me know your opinions on my ebay buy.  If I over paid it would be good info in case I like them and want to buy more.  Otherwise thanks again for the help, and I'll definately let you all know what I think of them after I have them awhile.

For now I'll close the ad as it pertains to my needing to buy.

Thanks,

Greg

Hey Greg,

I'm guessing you got these:

http://www.ebay.com/itm/PCC88-SEL-LORENZ-GERMANY-verys-strong-like-nos-matched-T...

I have a pair from Tubemonger bought some years ago and never really used them, but did listen to them the other day in looking for a National variation. I was concerned about commenting on them as they were not burned in, and above your budget on Ebay. So I put them in my MkIV that is burning in and they sound really good with a quad of Psvane 5881s (also just burning in, and sounded badddd! the first few days). These Lorenz are 2 mica. If you mouse over the ebay pic, you can see the pointy/ridged edges of the micas as they meet the glass, with the plates in between.

As I was listening the other day, when I was doing direct comparisons, I thought some tubes did better at coming close to the Nationals, and some worse, but when I just listened, each one of the 7DJ8s I tried was a nice tube at what it did. Especially with the MkIII bass and treble knobs.

I have been listening this AM to some Tungsrum PCC88s (cheap tubes still...I had these cryo'd) I had not heard for a while... with some JJ6CA7s, and the sound is very nice with music I have played so far!

Thanks Will,

Yep, same Ebay listing, he said he has 9 of them. Do you think I should have just stuck w/ something in the price range I paid for the Nationals.. $60 pair. In other words, do you think the Lorenz are probably no better or worse? Oh about the price point I listed,, I had sold 1 of my Rectifiers which gave me another $45 to play with. That why I spent more for the Lorenz. Figured what the heck, spend more and hopefully get into a higher level of performance. Tho I don't know if it necessarily works that way w/ tubes. Be interesting to see your impression on your Lorenz after they burn in.

anybody tried a Russian 6N23/6H23 in the 6922/6N1P input spot of their Torii? Steve is supplying the MA with 6N23's - gotta be a reason for this -He must like'em. They are pretty universally heralded as being really good sounding, well made and long lasting globes. I bought a pair of the Russian 6H23n's on recommendation for the 6922 spots in my Calypso... nice tubes, nice sound - more to my liking than factory supplied EH6922's for sure. I am thinking about getting another pair to try in my Torii... I'll bet somebody out there has already tried them in their Torii... please chime in.
I have the Upscale National 7DJ8's in my Torii right now. These were the first tubes I rolled from the factory provided 6N1P's. The amp absolutely makes more power with these and took on a more lively overall sound, but tonal balance still seems to be pretty balanced - I haven't noted a "negative" about them yet. I've only had them installed about 10-15 hours so far. Probably still some mellowing and harmonic bloom to develop I suspect.

I tried them some time back, cryo'd Russian ones from cryoset.com. To be frank. . . I didn't like them. I didn't leave them in a long time to bloom (it's my experience that cryo'd tubes take a while to come to be all they can be) because they just weren't doing it for me, too lean and crisp and pushy. I must point out that I don't prefer 6922 or 6DJ8 or 7DJ8 types in my Torii, these 6N23 seem similar to those to me.

Lon...

you sound like a stock 6N1P proponent... have you tried any different brands/variations of the 6N1P that you've found to be particularly to your liking?

Hi Greg,

The Lorenz tubes review I posted earlier in the CSP thread were Lorenz Stuttgart tubes with completely Gray internals.
Even the getter support and the getter itself are completely Gray.
This is the version which everyone raves about.

The Lorenz Company stopped producing their own tubes after some restructuring and bought and rebranded tubes made by other companies.
These are branded as SEL Lorenz tubes.
They are a mixed bag.
I have a bunch of them and they were either made by
Mullard Blackburn ("B" factory codes )  about 5% chance
or by the
Nish Yugoslavia factory with () factory code - majority 95%

Both the CSP and the Torii amps were designed with minimal parts in the sonic chain in order to preserve transparency.
So I'll expect the same tube sonics experienced in the CSP to show up when used in the Torii amp.

Hey LS,

Yeah I should have figured as much given the $90 price on mine.  I'm sure the ones you refer to are way more expensive.  Oh well.  I kind of figured I was throwing caution to the wind.  We'll see.   I'm fortunate to have many used cd stores around to by cheap and flip online at a reasonable profit to pay for the tubes.

I tried a handful of types and then tried the "super cyro'd" version from cyroset.com Took forever to "bloom" but when it did it floored me, I now use that in all my Toriis and CSP2+ . . . .
