It's buyer's market, they didn't have to bid unless they wanted to.

Seller didn't imply these are exact WE274 replacements (at least the way I understand his "Engrish" description), he merely stated that these are rectifiers, such as <could insert any rectifier tube here that could work in a 300B amplifier> (and GZ37 will work in place of WE274 if heater supply can handle the extra current requirement).

Besides, fools and their money soon part 🙂

Just think what they'd be worth if they were a matched pair!

They were !

They were also clearly marked as GZ37 .


Anyone who thought they were anything else, did not follow the first rule of EBAY ... "Read the Listing".

What gets me is the starting price of $699 !!

Now, where did I put that box of old tubes ... ?

I once emailed a guy because he was gonna pay a few hundred bucks for an old cracked AC plug that claimed to be "Western Electric" wire. The plug was that very old kind with two prongs slanted opposite each other. The bidder thanked me because the seller could offer no proof as to its origins. Sadly there were probably 10 suckers lined up behind that guy.

You're telling me over 60 years later that cloth insulated wire is as bright and colorful as the day it came from the factory?

I have had some WE wire knocking around, and yes it seems rather durable, and looks a lot newer than it should given its age.. (60+ yrs old in this case) Why I am not quite sure... Oh, it goes without saying I'm not really a fan - some claim aged copper wire is sonically superior to modern wire, what may be the case is that the metallurgy was better in the old days. Whether you can hear an actual difference or not is open to debate. (I can't)

It's not open to debate. Whenever this power cord debate opens up, it turns into a fruitless exchange with no proof of audible difference offered.

Unless of course one is not using the wire as "power cord" wire.
I was once tasked with stripping out a whole bunch of "power cords" from a huge auction lot the boss purchased. That wire was indeed metallurgically better than we could then (1989) buy. We stripped the insulation off, re-sleeved it in Teflon with Kynar (ultra high corona resistance) jacket. he used it in some ultra high freq. instrumentation amps.
Some was spirited away to be used as his speaker cabling (stacked arrays of 3@ r. & l. Dayton Wright X-10's). He swore to "feeling" a difference from his "old" 12 ga. silver & Beryllium Litz wire cables????
I never could..........but then I hated making those damn Litz wire cables anyway!!!! I'd been winding some very high power x-formers that were destined for Fermi Lab. and didn't want to see or hear the word ever again let alone make him speaker cable!!!

Actually now that I remember them (the Litz wire speaker cables)....other than being damned awfully expensive (12 awg 2400 strands Silver + 900 strands Beryllium with Kypton wrap), they sounded lousy. Muffled in fact..
My wife reminds me I was accorded the oportunity to seek new career paths as a result of my telling him he could not hear the difference between Cats yellowing and rain on the roof!!
But what really "did it" was my swapping out those cables for pieces of 12 ga. THHN stranded wire (in a placebo jacket to look the same as those Litz cables).... which DID sound good.
'course I could'nt keep quiet......kids will be young!!!😛

Sounds like a tremendous amount of work to me.. 😛😛 I make my interconnects from bulk cable purchased usually from Michael Percy - and some of that stuff is hard enough to terminate - I can't even imagine making litz speaker cable from scratch. I have litz speaker cables and I will say I prefer them to zip cord, but I guess I am deluded.. (It could also be that they have much lower dcr and maybe something else is going on.) 😀

kevinkr:
Your ears are likely correct. Such is my experience with "normal" Litz wire layups...but that Silver & Beryllium Litz wire was a very special layup that the Physics folk at Fermi Lab had specially fabricated at some enormous cost for their plasma field lab toys...we were simply winding the super cooled x-formers to their spec. Which is why we had the stuff to play with.

I too have some wonderful 18 awg. Cu Litz wire speaker cables that I fabricated years ago. Actually it is kind of fun as long as you do not have exotic metal termination issues (hydrogen embrittlement...had to be terminated in an inert gas shield..fused terminations slowly cooled, etc).
I was just being an *** and wanted to show him this particular wire sounded worse in that system.........and yes, I'd fabricated 5 or 6 full sets and tried them all (the Fermi "boys" ran them through their labs to verify backwave reflectance integrity, and a bunch of high freq. burst tests- none we reported to have problems). Several of the group there were "golden eared" audiofanatics too. They said the sound was muddy and other than stupendous treble ....


Anyway........sorry for the ramble down memory aisle. Back to lurker mode.

Thanks everyone I learn so much on these forums.
