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        :)

Ok, I'm resurrecting this thread.  I recently bought some RCA 5V4Gs and really like them in the Monoblocks...bought a second pair for the Torii MK IV and another single.  I know the Mullard GZ 32 is supposed to be the "Best"...or at least better.  But what about the Dario/Mini Watt GZ 32.  Is it made in France?  Holland?  Anyone heard it...comments please.  Mark.

PS...I'm trying to obey my unwritten rule not to pay more than about $50 per tube.

I've tried NOS Winged "C" 5U4G's, 5Y3GYS, and some others...

Not even close to the Mullard CV593/GZ32.  Not that the others were bad it's just that the Mullard was that much different.  But I doubt you'll find any in the price range you are trying to maintain.  Will suggested Tungsram 5V4G's and you probably can get these around the $50.00 mark.

Hate to tell you what I paid for the NOS CV593/GZ32's and I bought spares and I'm getting more!!  In my system and for my sonic tastes they are that good.  The interesting thing about the Mullards is that they seem too bring out the best of any other signal or output tubes I put in.  So now I've settled on the Mullard's and will roll around them so to speak.

I am going to be looking for some Tungsrams (curiosity only) once I recover from the price of the Mullards.

I am enjoying the RCA 5V4Gs so at some point I will try the Mullards.  How much did you pay?  What would be a good price?  When this thread was started it seemed to be $60, I'm betting 90 may be the best I could hope for...I see $120 a lot.  Mark.

Mark,
I paid $125.00 ea. genuine NOS Mullards. Yes it hurt.  Upscale does not list them anymore and evidently they introduced them at $35.00 ea. (always the last one at the party!!!)  The price of $60.00 seems to go back to 2011.

I tried to hyperlink an Ebay ad but didn't work for some reason... if you go to Ebay- CV539/GZ32 you should be able to see some Genuine Mullards for $90.00 from Taiwan.  This has appeared since I bought mine.

The ones I got are from the Canadian Distributor of SME Tone Arms.  You can find their ad on Ebay as well and his price is still $125.00.  Alfred is a really cool guy.  Has a long history in this market and has an incredible collection of tables.  He's restoring an Empire for me and modding it with an SME arm (I'm also into the vintage thing, it'll look great with the CSP, Zen, and the Omegas).  Because of the stellar service I get from him I'll be paying his prices.

In todays market when U52's are selling from $250 - $500+ and Western Electric 422A's are selling from $500 - $2,000+, good service and $125 is not all that bad.

Something else that put me on to the CV539's was positive comments from other forum members and...
