Nice neat bundling. Are those Russian KBG/MBGO PIO as couplers? They look good in there. smily_headphones1.gif
I've had my eye on some of those for between stages to replace some polypropylene I currently have.

Glenn, do you think the 6336s work better with certain headphones and the 6AS7s with other?


I like the 6AS7 better with higher impedance headphones like the HD-800

but with lower impedance head phones  120 ohms and lower the 6336 sounds better.

Yes they are the MBGO I only use these and Sprague vitamin Q for coupling

The bypass capacitors are Sprague Atom For electrolytic I only use

Sprague Atoms or BC components a little expensive but worth it.

Looks very nice.

The BL63 tube

 

This is a tube that people ether love or hate.

Playing with this amp and tube all morning I like the sound the problem is the operating points

of the 6SN7 are different then a BL63. So when somebody just puts a BL63 in a amp that is running

a 6SN7 at low current it will sound bad.

In this amp I run the 6SN7 a little hot so the BL63 sounds good it is a compromise though the owner

wants to be able to run the BL63 as well as the 6sn7.

I would like to make a amp that is made for the BL63 so it can sound it's best.

Clayton,
 my cousin finally dropped by to pick this up. he wanted me to thank you VERY VERY much. thanks!

I really think the Crack sounds constrained compared to the Glenn's amp. Don't get me wrong though - I liked the Crack and Valhalla, but I am selling both. If you love tube rolling, a Glenn OTL is great. If you like to tinker, the Crack is for you. The Bottlehead forums are full of crazy mods folks have done to that amp.

 

After thinking about it, I'm going to go put my T1s on now. :biggrin:

Have you tried the speedball upgrade and upgraded tubes for the Crack?

Constrained in the soundstage?

post #5306 of 10136

I do have the speedball in my amp. As for tubes, I really only chanded the driver out. I didn't have any extra rectifiers at the time. Currently, it's in a closet.

 

I guess you could say the sound stage was smaller, but it's more like the music was pushed. Glenn's amp has flow. Does that make sense? I could be just talking out my ass here too.

BTW, if anyone is interested in an NOS pair of Centron 6336s let me know via PM.  I bought a quad but only need a pair.

post #5308 of 10136
That reminds me, I have some of the big Russian rectifiers (5U8C) discussed here in the past. Glenn made me an adapter for the OTL. It's very 596 like, but more power less detail? I'd have to revisit the tube I suppose. If anyone wants one, shoot me a PM.
post #5309 of 10136

Right now I am driving my speakers with Georges OTL headphone amp with 6336 output tubes.

it would be better if  they were 16ohms but not bad though.

Tremendous frequency response but limited power.

post #5310 of 10136

I am listening to my Glenn OTL with my T1s.  The tube compliment is a pair of GEC CV2523s, 1 GZ37 and a Sylvania 6SN7 WGT.  This is a perfect combination.
