You are the best of the best.

 

My sister came to visit me from Hawaii and when she saw your amps she said, "It is Frankenstein's laboratory!"

And I guess the real question is, if the Blackburn and the thin High Wycombe can be had for about the same price, which is the better buy?

 

Well, I picked up a skinny Cossor 53KU and it does indeed appear to be a Mullard. However, at least in this case, it is not a Mullard GZ37 as we had surmised... The Phiips code for a GZ37 is "IS". The code on this tube is "rS" which translates to a GZ33.

 

An easy way to distinguish them from pictures: the Mullard GZ33 has silvering on the glass between the second and third micas, while the Mullard GZ37 has a clear top.

 

An interesting find. :)

 

 

 

Edit: Changed GZ34 to GZ33

rS is GZ33 here, though. Both GZ33 and GZ37 may appear as CV378. I don't think GZ34s of this shape exist.

 

Edit: … and a nice shape it is. :smile_phones:

Yeah, I think you are correct. :)

on page 12:

 

rS = GZ33, CV378 and GZ34 made in Eindhoven.

 

As this was made in Blackburn, this is likely a GZ33.

I'm with Oskari on this one, GZ34 in this shape?

Hi, Glenn:

 

Do you know if damage was done?

 

I took my Decware CSP2+ out of storage. You modified this preamp in 2011. The amp had all of its tubes in place except for the rectifier. I intended to put one in after I set up the amp. I plugged in the amp but didn't realize that the on/off switch was already on and the amp powered up without the rectifier. I shut it off a minute later when I discovered that it was on.

 

The amp sounds fine but wondered if I damaged anything internally.

 

Here are the photos (taken in Dec. of 2011).

No worry

Without the rectifier nothing in the amp will get any power.

So it was just dead without the rectifier no damage.

Many thanks Punit for giving me the chance to experience the Glenn's OTL amp magic on my HD800! If you remember, this is the first one that I've selected to try even though you have a batallion of TOTL amps in your 'showroom'. The first time I tried it I understood easily why so many are raving about Glenn's amps. With the HD800, the soundstage is holographic, instrument separation and placement stood out, treble is well controlled but what specially impressed me is how hard the bass hit and the drums kick! Sounds so lifelike and natural! With this combo, I can loose myself with the music and just enjoy it. Your other amps are excellent too and you know how I enjoyed Master 9 as well which is very similar with my Rag.

P.S. Still drooling with your HE-6! So sweet sounding headphones!

Cheers

I think many, including me, have assumed that all C3G were manufactured by Siemens. However, a picture of a Lorenz and a Siemens, both unsheathed, posted in the Little Dot tube rolling forum, suggests that there might have been at least one other manufacturer:
