And didn't like it. It turned the presentation quite dark. Slammin' bass but no sparkle.I have a 5Z4 coming. It has an indirectly heated cathode like a GZ34 for a slow warm up but the voltage drop and current capability of a 5Y3.
I have some vintage Sprauge Vitamin Q and Russian K40 oil caps coming also...

Try the 6106! It has the bass slam of the GZ34 and the sparkle of a very good 5Y3. Only complaint I have is that it takes 45 seconds to get the high voltage from it (from Red to green of the LED indicator), otherwise it sounds perfect on my Cornet II in my system.Currently using TD 124 MKII and SME 3012 with the original (Sugano) Koetsu Rosewood. Try it, you might like it.
IIRC most US made versions of the 5Z4 are a metal tube?Brimar made a glass 5Z4 which look to be very much like a GZ32.
Then there is a 5Z4p which would be a Chinese equivalent of the GZ-32 and is not a half-bad tube, I have used one in my tube line stage is sounds about the same as the Mullard GZ-32 I paid big $$ for.
I have a 5Z4GT (glass? I hope so!) coming from ESRC. $5 was not much to gamble I suppose...Thanks for the tip on the Chinese version! Anything Mullard is expensive now!

have you tried that?
My 5Y3 stock is mostly from an old TV repair shop I bought out in the late '80s. Lots of GE and Tung-Sol with Sylvania, RCA and Ken-Rad thrown in.Telefunken, Mullard, Brimar, Valvo, Mazda and Siemens all were absent in that buy. Luckily some stuff hasn't hit the rare and pricey yet.

...Lots of European 12**7 types. Those were acquired the hard way. I paid up to $15 for some of those (Actually more for some really old Telefunken smooth plates from Andy but that is a long story).I haven't gotten to Amperex yet. I currently have a really sweet pair of old Mullard ECC83s in there as well as a super tough, mil spec, 12AU7 equivalent (RCA command series 5814).
I love a set of nice Bugle Boy 12AX7s in my ARC phono section.
I need to put some hrs on the Cornet2 yet as I just installed Auricaps in it last night. In a few days I will really be going willy-nilly with the tube rolling.
I use Amperex 12AU7's in the front end of my amps tho. Sweet tubes. I just switched my Heathkit W5-Ms back over to GEC KT66s and GZ34 rectifiers today.
Nothing like a new component to inspire a fella to re-do the whole system. Ahhh, audiophilia...
there are five or six amps and pres waiting to be built from that pile. ;-)

I have half a dozen tube caddy's stocked like that one, and more in the shed.I am sick I tell ya...
It helped to be bitten by the tube bug 20 years ago, things were better then...
