Opinions on rectifier tubes?
12/15/05 at 00:12:59
 
Hello,
Now that I have the Select mono's drivin my 511B/902 horns I would like to do some rolling.

My current tube compliment is as follows:
Golden Dragon 274B's
NOS rca 6bq5's
JAN 6922's

This is the recommended combo by charlieboy who I accuired the amps from.He also said that I could probably do better with  different rectifier tubes.

What I am hearing sounds fantastic,but gotta scratch that itch...

So what are some recommendations,impressions on rectifier tubes.

Being new to this rolling I'm not sure what to look for,what works,what doesn't,to many variations and possibilities.In time things will clear up but for now any suggestions would be a great help and starting point.

Greg

Ditto.

A good second to the Mullard GZ32 would be an RCA 5v4, which is a little less pricey. The RCA is very very nice and a little less pricey, but not quite the Mullard.

I agree with the Mullard GZ32 recommendation.  It was the best in my Select before I sold it.  The rectifier was snatched up pretty quick after I sold the Select.

Questions.

Can this Mullard GZ32 be used on a CSP?

How long will one last?  Is one on a CSP all I will ever need?

I have been using RCA 5V4G in my CSP. It will last at least 5 to 10 years I believe.

I have been using a Ruby.  Lots of people don't like the sound of a Ruby, but it seems to fit in my system.

I haven't been able to beat the 5y3 family in my CSP.

The GZ32, 5v4's, 5r4's, 5ar4's, 5u4's work in my select, but don't fly in the CSP like the 5y3. The Sovtek 5y3 works ok, the Mullard 5y3 is incredible, and the Bendix red bank 5y3 is very nice, for my system.

I love the Mullard GZ32 in my select, but don't dig it in the CSP. Second best to the 5y3 in the CSP is the Cetron 5r4 or Sylvania 5ar4, but the 5y3 still wins. ymmv.

Karl,
Have you tried the Mazda 5Y3. That is a verrrrry nice 5y3. I was a little partial to the RCA 5Y3 in my C but have since changed my mind and the Mazda is a clear winner. Can be found still at reasonable prices too.

Thnx Mike,

I haven't yet tried the Mazda, but I'll poke around and seek to get one. Right now am using Bendix Red Bank 6106 which is very very nice, which was recommended by Eli. The Bendix is not so easy to find.

I'm  inevitably hoping to replace a Mullard 5y3 that died. THAT one was really something; it had noticeably the most liquid sound and best separation of instruments of ANY I've tried.

Another rectifier, IMHO, that sounds very nice in a Select is a Raytheon 5U4GB. Still looking for a (reasonably) price Mullard GZ32 though.

The other tubes I got with the amps are:

Svetlana SV83's
Siemen 6922's
Stock 5u4's(chinese origin?)2 pair black bottoms and red,black bottoms have 5z3p on glass red has 5u4g made in china on glass.

I have'nt tried any of these yet,everything is too new and I am trying to get a feel for the sound.

I believe I have the best combo in now?

Thanks everyone for the ideas,I know have an idea what to look for at least.
Saw some Mullard gz32's for around $60,did'nt know if this was a good price or not,they were out of Great Btriton on ebay this am.

I'm not the biggest expert around, but I haven't seen them for much less than that, and have seen them for more. My experience with this particular tube is I like it so much in the select I'd pay that price if I didn't have one (if the seller was trustworthy).

Hi Greg, I bought my Mullard 5V4/GZ32 from Upscale Audio about a year ago and it was $35 at the time. They are now listing it for $60! Ouch... But it sure is a sweet sounding tube...

I wonder what the rationale for that sort of a price increase is.  Is greed a possible motivation?   Kiss

Mullard GZ32s are fast becoming as costly as Mullard GZ34s.   Angry  Since the RCA 5V4G is nearly as good as the Mullard GZ32, that's the variety I'd be trying to obtain.

The Mullard GZ32's I have are marked CV593 instead of "GZ32" which is a military number, but they're supposedly identical. If they can be found perhaps they can be had for somewhat less?

I just put a CV593 / GZ32 I bought off Kevin @ Upscale years ago for my little 2watt Zen in my Rachael and holy cow, what a big difference over the 274's that Steve is shipping in the units now. I used the 274 for about a year and bought a cryo'ed version off of Ron @ Cryoset but this GZ32 is really, really nice so far. Happy listening, Chris.

Hi Chris,
In my Rachel in my computer room system, I'm running a Sophia Electric 274B in the rectifier position. In the power I'm running 1960's RCA 6L6GC Black Plates and Zaerix ECC88/6DJ8's.

Love the sounding I'm getting currently. This is the system I just added a Rega RP6 and Nova II phono pre, running a Dynavector 20X2H.

Chris, how would you describe the differences between the 274b and the CV593 / GZ32 in the 2 watt Zen?

When I go my 2 watt Zen, Steve was supplying a 5U4, I haven't tried the 274 in the little Zen. But in our Rachael I feel that overall sound stage is a little bigger with the GZ32B than the 5U4 or 274. But now I will have to hook up the lil'Zen and try the 274 in it. Also in the Rachael the background just seems ''blacker'' if that make sense. Sounds seem to come out of nowhere. Actually last night playing some Steve Hackett everything just seemed more dynamic and the differences between his guitar tones was much more obvious. Very tough to put words to emotions sometimes. Happy listening, Chris.

Nice, thank you. I'll be receiving my 2 watt zen any day now and can't wait to try different tubes.

Pursuit- My only suggestion would be to run the stock tubes in the unit until you have a firm grasp on the amps sound. It changes quite a bit over the first few weeks, but just listen often and get a lot of hours on it. Decware is the most amazing product lines I have experienced and you want to be sure the changes that tubes make are noted instead of the capacitors settling in. Happy listening, Chris.

Hello pursuit,
used the stock Ruby's, Valve Art 274B, NOS RCA 60's vintage ( I THINK black plate ), and the clear winner by a long shot was these :

http://www.ebay.com/itm/2x-5c3s-5U4G-5U3S-5U3C-Svetlana-Black-Plate-Russian-Rect...

Now the ones I have are late 50's-mid 60's variety. If you can get one of that vintage, go for it.

I've got eight ( was going to include them when I sell my Select ), but I could send one or two your way if you like. Send me a PM if you're interested.

So I've got to agree w/ samb0357.

Incredible tube.

Cheers,        Crazy Bill        :)
