Speaking of tubes. I actually bought some for my upcoming Telemachus I'm building for myself

First I got these WE300B's. It's going to be interesting to hear the difference between these and the Gold Lions I got. Don't expect a detailed review of these tubes as I'm terrible at that kind of stuff lol. Definitely the nicest packed tubes I ever got that's for sure.






I also got these rectifiers. Mullard GZ37, RCA 5R4GY, Brimar GZ32 and Brimar 5V4. The 5V4 is really not recommended in Telemachus as the maximum voltage allowed is surpassed but I'm gonna try it out. As I said, NOT recommended though!
I'm looking forward to playing with these!

Thanks for sharing about your tubes. First time you ever did. That packaging for WE300B is really nice. They retail for about AUD$2500 for a matched pair here.

Thought the GZ32 is a no no in the Tele?

No, should be fine.

It depends on B+. If it is signficantly higher in the Tele than a typical OTL, it will fail.....

It depends on the secondary high voltage AC winding and the current draw of the amp. The GZ32 can put out 250mA with 2x350V input (cap input filter, like the Tele) Telemachus is 2x400V and draws around 175mA so should be fine.

This is good to know. In Glenn's 300B amps, GZ32's failed. But I think his circuit was closer to 2x500V (cap input) and the best the GZ32 can put out at that voltage is 125mA. But the amp wanted more and the poor little GZ32 just couldn't do it.

Rectifier day. I can use these in both Odyssey and Telemachus.

Sittard GZ34 is in Odyssey so cannot be displayed.

From left: Emitron 53ku, Mullard GZ34 f33, Miniwatt GZ34 metal base, Mullard GZ32, Mullard 5U4G (Made in USA ), GE 5U4G and USAF 596 from Woo.

Did I say rectifier day? Yes and I'm rolling rectifier today. First up is the understated Mullard GZ32. Coming from Sittard GZ34, this has more texture and I was shocked that I love it, as much as the GZ34. There is more body and just a little more warmth but the tone is so clear and NOT sloppy. There is a liveliness here that engage me with the music. It's smooth and tactile at the same time.

If anyone had told me that rectifiers don't make a difference to the sound, I wouldn't believe them now because clearly I am hearing a difference. The rest of the tube combination are the same and they are - Tung Sol 6SU7gty (6SL7) and Philips Miniwatt (labelled Mullard) EL34 double D getters.

And I agree. To my ears, the Mullard GZ32 is the best Mullard rectifier. I like it better than GZ33, GZ34 and GZ37.

I may end up agreeing with you but I'm not finished going through the rectifiers yet. It's now 53ku's turn. The sharp clarity is down a notch but the texture and bass is up for sure. I listen to Daniel Castro's I'll sing the blues for you and it's right at home. Similarly Norah Jones's Don't know why and Jimmy Barnes's Stone Cold and Joe Bonamassa's Drive !

Happy to finally received my telly.

Just enjoying with lcd 4z and heddphone. No hum and hissing whatsoever with me. Even with my sensitive Audezes.

Amazing to have that 300b sound with the agility of SS. I'm very pleased

 

[whirlwind]

I like Mullard GZ32 also...like the 37 too.

Haha, you have knobs like mine, nice blue jeans.

I still can't figure out what that is. So I'm naturally intrigued.

 

[alvin sawdust]

Mullard GZ32 doing rectifier duties and it sounds how I hoped it would, alive and deeply engaging.
Two live albums, Fink & The Royal Concertgebouw Orchestra and Donny Hathaway: These Songs For You Live sound utterly beguiling.
I've got things to get on with but I can't get my backside out of the chair

God I love this tube!
