Hello pankon,
Which version of the E83CC you have on your preamp?
The frame grid version (code 37) or the NON frame grid one (code 32) ?
Has anybody tried the frame grid one ?

Hi Aris,Originally Posted by Gibo69
as far as I know, all Tesla E83CC are frame-grid type, irrespective to whether their code is 32 or 37. So, they should all be very, very good ones.
Cheers,
Panos

I have tried both and prefer the frame grid (37) version. The non frame grid are ok but not quite as good.

If I am not mistaken, the non-frame-grid Teslas are called ECC83 (in contrast to the frame-grid, which are called E83CC).

Thank you very much.
Not all the the E83CC are frame grid....as far as I know only the code 37 are frame grid...the code 32 (marked in yellow) are non frame grid...
Check at www.jacmusic.com under TUBES -> NOS TUBES-> TRIODES->ECC83 page

You're right pankon...Tesla E83CC code 32 and 37 are frame grid....my bad..
Its so confusing !!
This is E83CC code 32 framed grid : http://www.jacmusic.com/nos/images/E...SLA-BOXES3.jpg
This is E83CC code 37 framed grid : http://www.jacmusic.com/nos/ECC83-part-numbering1.html Check the picture with the 8 tubes at about the middel of the page...its the third from left (tube nr.3)
Then there is this one too....E83CC code 32 yellow marked : http://vintageamps.com/plexiboard/vi...p?f=13&t=51565 check post nr. 9, second picture...
Mr. de Walle of Jacmusic has on stock the 32 version with Crossed Sword and no gold pin...he say that they were bought by the military services. (the first link above).
