[Amps] Any experiences with "powergridtube"? (YC156 hunt)

[DAVE WHITE]

I've not come across that seller before.  Does he mean $550 per tube?  Also he's stated that you may not get the one in the advertisement, so although the picture is of a new looking one, you may get a blackened and half-melted dud in the worst case scenario - though I'd hope to have a bit more faith in human nature than that...

Just Goolging to find out a bit more about that tube, I saw this http://www.directivesystems.com/YC156.htm 

...which seems like a nice, neat bit of construction.  19dB gain from a triode?  Strewth.  Would that be a bit of a beast to hold down in a multiband amp?

Price-wise, since I just paid GBP200 (about $280) each for a couple of new though rather old stock Eimac 3CX3000F7s I think $550 may be a little steep, though I've never bought a YC156 so don't really know.  Still, it looks like one hell of a tube for the money

Hope this helps.

Oh, and "flame wars"  ?? on this group?  Ahem <cough> surely not....

  I'm looking to buy a couple of YC156's for a project, either rebuilt 
or full-output pulls.

There's a current eBay auction by "powergridtube" that lists 5 tubes 
"cleaned and laboratory tested to full output", although no specific 
guarantee is given. Any experiences with this guy? (replies off-list ok 
to save feelings and avoid flame wars)

Thanks,
