In my opinion, the Mullard GZ37 is not as good as the Cossor. However, I think the GZ32 is as good. In fact I think the GZ32 is the best of the Mullard 5-volt rectifiers, better than the GZ33, GZ34 and GZ37. The major difference is that the Mullard GZ32 is a bit sweeter than the Cossor.

Such an old post but I'm getting 2 x Mullard GZ32 to supplement my Cossor 53ku for the WA22. Looking forward to it !

It's pretty quiet here, so I thought I would talk about another tube that I think no one else is rolling. lol

Below is an EL41. As some might remember, I have been rolling EL41 for some time now. The EL41 is a miniaturized version of the EL3 / EL11, but slightly less powerful.

Recently I came across some EL41 manufactured in Barcelona, Spain. And interestingly, this is the first time I have ever seen Philips production made in Spain. Being very curious I grabbed them.

The Philips production code is SY M43 which indicates they were manufactured in 1949.

And from the Philips Valve Code page,

S = Lampara "Z", Barcelona

And searching for Lampara "Z", Barcelona, I found this Wikipedia article:

https://es.wikipedia.org/wiki/Lámparas_Z

All in Spanish! And while I studied Spanish in high school, I have forgotten nearly everything. lol

However, as best as I can make out, it would appear that Lampara Z is the Sociedad Española de Lámparas Eléctricas Z (SESEZ). It had a very close relationship with Philips starting in the 1920's, but it is not clear to me if SESEZ was a totally owned subsidiary, or just an affiliate. Anyway, they were located in Barcelona and in addition to lighting products they also manufactured the EL41.

And while it carries the Marconi brand, the tooling indicates that they were definitely manufactured on a Philips assemblyline. I hope to clean the pins and roll them in soon.

Very interesting Gib and while I haven't post here for a while, your talk of the EL41 spark my interest in another tube - the EL95 as used in the Auris Euterpe. This is one sweet sounding dac/amp whether using it's own dac or the Chord Qutest. It's not cheap though. Auris amps aren't cheap.

Euterpe is very clear, tight, punchy and fast transients with Audeze LCD-4 and has power to drive it no problem.

Do you know anything about EL95 @gibosi ? This is the first time I've heard of it - in both sense of the word.

It's also a headphone stand !

It looks quite a bit like an EL84. Since you mentioned it's downrated compared to the EL11 I wonder how closely it comes to being an EL84 electrically.....

I think these Marconi/Spain 6F6G can be used in the EL3N amp:

I like them a lot in my gear.

While I have no experience with the EL95, I do have experience with the EL42, a predecessor:

https://www.radiomuseum.org/tubes/tube_el42.html

And I like the EL42 very much. It's very quiet and Blackburn Mullard and Sittard Philips are among my favorites. And fortunately for me, the EL41 and EL42 use the same adapter. That said, can't say for sure how the later EL95 compares.

"The very successful EL84 is the last development step from EL3 via EL41 to the final point of radio output pentodes...."

But while I have no experience with the EL84, I do like the EL41, Blackburn and Sittard especially. And in terms of looks, these very early Sittard EL41 are pretty neat:

Thanks. EL42 predecessor are EL8, EL13.... both of which I've tried in GOTL. I see the connections now... historically and in tone. Now wonder the Euterpe sound refreshing, energetic and vibrant to my ears.

Also thanks to your post on the GZ32 rectifiers which I quoted above. I had GEC U52 but sold it off together with all my GEC 6as7g. Thought I was leaving tubes lol. Now I'm left with the beautiful sounding Cossor 53ku for my WA22 amp. I'm going to pick up these pair of Mullard GZ32 (less than 50 hours - from a friend so I believe him) for AUD $160 which I think is very cheap. No?

Now tell me if these are the real Mullard GZ32.

Been eyeing those for my 6EL3N amp for a while now...

Don't hesitate. Great tubes from a great seller. Compare to the price from the Italian sellers...

I'm back to report my findings of the Mullard GZ32 against the Cossor 53ku that I have. I bought 2 GZ32 and you're absolutely right about the GZ32. It does sound sweeter than the Cossor although the latter has warmth which the GZ32 has too. Turns out $160 for 2 nearly NOS GZ32 is a steal.

These may be the best rectifiers that hardly no one talks about...which is great as it keeps the price down

Priced very nice too.

EL84 is a wonderful tube. It delivers the music clean in the right application. Not cold or bright but clean.

Rolled in the Spanish Lampara "Z" EL41s and they sound good!. But of course, those of us with Glenn amps know that almost everything sounds good.

A 596 rectifier, a pair of Chatham / Tung-Sol 6528 (similar to the 6336 but with a mu of 9) and a pair of Lampara "Z" EL41.

I miss the tube rolling days. I don't do much of that now. It's amps rolling instead and headphones.

and I did miss the Cetron 6336 tubes. It's awful I released so many tubes with the sale of GOTL and Studio Six. That's when I slid off tubes by almost 50% but I still have Wa22 and LF339 and who knows what else later.
