Preamp Deal of the Century

Hello Abe. The 6v6 is a beam tetrode similiar to the 6F6 and will work as regulators in the supratek syrah, however, I doubt it will sound better than a 6l6, my experience with any of the metal tube types has always been a disappointment. The early 6L6's and 6F6's were metal tubes as well.Give them a try and see what you think.

Hello Jyprez. Whom would you be referring to sir?

Tube rolling results:
.
First off, thanks ever so much to Ecclectique, Bwhite, Asa, and Jazzdude for all your help and advice in recommending NOS tubes for my Cortese.
.
The results of the NOS tubes have been nothing short of stunning with regards to the enhancement of the bass control, sound staging (expansion of and delineation), detail without giving up warmth / emotion, more life like sounding instruments, and much more musicality. I loved the Cortese with the stock tubes and now with the NOS in place and broken in, the listening has become an overwhelming and tireless experience.

.
I rolled the following tubes into the line stage section of my Cortese:

Nos Neotron 6SN7's
Nos Mullard EL 37's
NOS 5AR4 Philips Miniwatt Holland Metal Base NOS 1957 Tubes

They were all quite expensive, but in the end well, well, worth every penny.
.
I just ordered a pair of NOS Tungsol 6SN7 Black Glass round plates and will let you all know how they stack up against the Neotron 6SN7's after they arrive and are broken in.

It took a good solid 200 hours of continuous running time for the NOS tubes to fully break in before they really showed what they could add to the sound (EL 37's took a particularly long time).

For those of you rolling NOS, give them a bunch of hours before evaluating. The improvement from break in is huge. The value for the extra money invested in NOS is clearly available.
.

Ecclectique,

Much thanks for the valuable info. Reason for asking is because I had a really fortunate day today. A friend of mine who works at the University (Southern Cal)gave me a big box of tubes which are remnants of the tubes (electronic shop they had)in storage since the 70's. My score are as follow (all NOS, most with boxes).

2- RCA 2A3
4- KenRad 6V6GT/G
2- KenRad 6F6 (the metal ones)
2-GE 6sn7GTB
2-KenRad 6sn7 Clear Glass
2-RCA 6L6 Metal
2-Sylvania 6sn7GTA Green Lettering Chrome Top
2-CBS Hytron 6SN7GTB
2- GE 5881 Brown Base
4- Telefunken 12AX7
4- Telefunken 12AU7
8- Amperex Bugle Boy 12AU7
2- Amperex Bugle Boy 12AX7

and lots of 811, 0DA's, 807 etc.

Since I am waiting for my Syrah, I like to know which I can use as replacements of the tubes stated on the website.

Thank you and I really appreciate your help!

Abe
