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.

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.

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 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.

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.

[quote author=yosemite_sam  link=1134609179/0#7 date=1134695131]What other tubes are you using in CSP? [/quote]


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?

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.
Is that the going price? [/quote]

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).
