Thor:
I just refreshed my memory (WWW search:-) and yes, the original Svet's had a "C" logo. Triode Electronics sells the original "C" tubes (no longer branded "Svetlana") for $60/matched quad. From what else I have read people are having cables cryo'd for as little as $10/lb.
If curious and the $165 is an obstacle perhaps see if a less expensive tube dealer (such as Triode) will forward your purchase directly to a cryo facility with the tubes then being returned to you following treatment?
You may not save much, if any, on S/H, but less time/distance in transit is always desirable with larger tubes.
Kind of OT, but for $165 if my amp did not require closely matched output tubes (most do not) I would put together a good used quad of Mullard XF1's or XF2's from Ebay. Great sound and if they are 90% test, or so, they should last for many years in some circuits.
There is another tube dealer Jim McShane (sp) with a vintage Harmon Kardon site who I think may now offer cryo service @ reasonable prices (not certain though) and maybe even Triode offers such (have not really looked into cryo much).
