el34 cryo'd tubes


Using EL34 Svetlanas,which work well,but wondering if any have tried a current production Quad of el34s with a cry'o treatment. Toying with the idea of trying a cryo'd Quad but thought I would ask first to see if its really worth it or not. Using Thor TPA 30 watt monos with Svetlana el34s at this time.
Thanks to all !!!!

Dekay: Thanks good point. I am generaly very happy with the Svetlanas I am presently using but have seen Tube World praising there EL 34 Svets' cro'd (at $165 a quad) and have been tempted,but haven't heard quite enough feedback yet...
Thanks again Thorman
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).
Thor:

I would like to mention that I was no in no way disrespecting Tube World. I have never done business with them, but if this is Brendon/Brandon's (sp) business, then he comes highly recommended by people I know (& no I did not receive an email from them in regard to my above posts:-).

In context, when I was away from our home "far" too often working (been off work four years now) I would not have blinked an eye @ an $80, or so, "taking care of the details" charge as everything takes time (time is money when operating as business), plus I could easily afford it then.

I was just noting that there are usually less expensive alternatives to those who prefer doing the grunt work themselves, which is pretty much a universal concept.

Of course, in the context of this thread, the responsibility of finding a reputable cryo facility (if not going through a dealer -w- a guarantee), would be up to the individual and hopefully the tubes would not end up being placed between layers of "Hungry Man" TV dinners.
Dekay: I agree. I had'nt actually thought of buying a quad and sending them out to be treated,which is a good point you brought up. My cables are from Ridge Street Audio and he does cryo tubes.His prices are reasonable also very reliable too ,so I guess maybe i'll check that option out first.. Thanks
