What tube's are you guys using?
01/31/13 at 17:11:40
 
To appease my Decware addiction I just ordered a ZP3.  In perusing the forum I didn't see too much info on tubes used.  I am going to stockpile a few so I'll be ready to roll when it arrives in 2-3 months time. Curious to know people's positive and negative tube impresssions.

Thanks in advance.

I've tried about six rectifier tubes in my ZP3 and the clear winner for me is an old RCA 5Y3GT that just really anchors the tone foundation for me and also gives the most natural, unprocessed presentation of the six.

I bought a pair of Raytheon 12AX7s from Mike here on the board that really nail down that tube type for me, a matched pair. Interestingly I've found that the 12AU7 spot is very influential to the sound and I have handfuls of this tube type. I alternate lately a Telefunken, Mullard and Raytheon (I think, maybe RCA, supplied by Decware). It's taken me weeks to get to the point where the sound is stabilized and I can really make solid judgments. . . . This preamp is a lot like the CSP2+ in that aspect.

In the OA3 position I've also tried six tubes, and also two OB3 tubes. The Sylvania bottle type OA3 that Steve sent is very good, and I also am still using an RCA bottle type. OA3. An OB3 is interesting with this preamp, but in my system always just comes up a bit short in the weight and heft areas.

I know you're really going to enjoy this preamp!

I`ve  liberated a Mullard GZ34 from my old amp which has been replaced by SE341`s, and put the stock back.
Looking forward to popping it in the ZP3 after new amps and cables have settled down.

JD, you must be checking out a variety of tubes in anticipation.
I did the same and have a small selection.
No real favs between TFK, Brimar, Mullard, and a P.miniwatt in the 12au7 spot.
GE, RCA, Mullard, Phillips, for rectifiers of different configs, ie, 5Y3GT,
5R4GY etc.
0A3 pos....Raytheon
12ax7, seems I`m happy with Sylvania x3 mica.
Still a few to get but there comes a time when you say
enough for now. Well maybe a 12at7 or two.

Ones that got away for now....square getters....bugleboys...
the usual suspects,
Some GZ34 rectifiers are big bucks. My Mullard wasn`t to bad. Listening with it in now sounds good....or different.
Good hunting   Smiley

After a few months of letting it season I'm really enjoying the ZP3.  Using an early fifties rca 5r4gy and oa3 teamed with nos mullards all around.  Rega p6 and ortofon black 2m (with 2mm spacer) cartridge are all combining for an awesome sound.  
You can't beat vinyl.

I don't think you can do that.  I have tried many 12AU7 and it's variants, maybe more than a dozen, in the furthest back slot and about a half dozen 12AX7s and variants in the front two slots. Current tubes include two RCA Triple Mica Black Plate 5751s and a RCA Triple Mica Black Plate 5814 in the 12AU7 slot....a winning combo.

PS...my guess is that you could use the 6N2P in the 12AX7 slots but i wouldn't do it until you find someone who has used them with success or you ask Steve.  They are very inexpensive though...a good thing.

Steve D advised you can use 12AU7 in first 3 slots of ZP3 but, gain will be greatly reduced if used in either 1st or 2nd slot...or both. My listening level is around 9PM with ZP3 into Superzen so I may give a 12AU7 a shot just out of curiosity.
