HI Wayne, I got them at the Tube Store; $89.95 for a matched pair.

I've ordered from these guys several times and they're great.
I like them even more because they're Canadian.

I received my pair of Electro-Harmonix 2A3 Gold tubes today. I'm so busy I barely had time to write this post, and so I haven't plugged 'em in yet. But I'll surely do that at some point this weekend and then I'll write back. Thanks again Seeker for the suggestion.

These are the changes I put amps through:

(1) The .1uf metallized polypro interstage coupling cap was my first stop. Doubled up to .22uf for starters, tried VTV silver PIO caps first, but ended up with Audio Note copper foil PIO's. (No cries of "Foul!" please. I don't distribute the parts. In North America PartsConnexion.com sells them.)

(2) In my case, the iron underwent a wholesale change next. (If I were to do it again, I might do the third step 2nd.) The parafeed OPTs were replaced by a pair of nickel MQ's. I upgraded the parafeed chokes as well, again with MQ's goodies. This yielded a spare pair of chokes which can be directly subbed for the big-ass 1.2kohm 10w wire wound resistors. A no cost upgrade which yields much smoother, more refined sound.

(3) The 3.3uf parafeed caps went next. Again, metallized polypro are not the nicest sounding caps, but they are cost effective. In my case, I scored a pair of Western Electric PIO caps from Mike Lefevre while he was in a garage-cleaning frenzy. ;-0

Note: Early on, I had subbed Black Gate caps into the PS. Heard next to nothing, which is assuredly NOT the case in other applications. The parafeed topology seems to minimize the sonic effect of PS cap choices. I wouldn't bother with them till I had run out of other things to monkey around with, if then.

Yeah, it's all been covered on the Bot Forum, but, as somebody else already said, "yer here, right?"

Foul!

I don't really know why I said that. Just 'cause you said not to, I suppose.

Hey, is the Paramour amp you brought to Lima the one you're describing here?

Yep, that would be them, alright. I forgot to mention in the first pass that obviously tube rolling plays a big roll. I had (and have) TJ meshplate 2A3's. I preferred them to the Valve Arts and Sovteks. A pair of ancient RCA's were lovely till one got feeble; that's when the meshies came on board.

At that show I had one dead and one live input/driver tube. (One didn't enjoy the drive to Toledo.)

I remember your having a bad input tube. Easy swap though, easy fix.

You might have seen that I purchased a pair of Electro-Harmonix tubes. They sound real nice and no more Geiger-counter clicking sound from the Valve Art's. Do your VA2A3's make that Geiger counter click?

I'm jealous about your RCA's. Those are what everybody wants at $300.00/pair. I'm slumming it with my $100.00/pair Electro-Harmonix. But the build quality looks very similar to the TJ Meshplates. If you don't look at the labels on the base, inside the glass you can't tell 'em apart.

As the rest of the worls knows, I won the TJ Mesh (sortaplates) in the 1,000,000th post contest. They sounded detailed, had good bass and were an upgrade? But the Valve Arts were quieter and more Musical(?) (easier to listen to) and BLUE.
