Hello All,
I have 3 matched pairs of NOS Vaic AVVT 302B tubes. I am wondering if people might have a sense of how much they are worth.
TIA

Since they aren't really a plug and play replacement for a 300B, your best bet is to put them on eBay and hope that there are some folks floating around who have built amps specifically for this tube.
Yeah, I'd put a pair up on eBay and see what happens. I had some Svetlana SV-572-10's that went for decent money, but not until I tossed them onto eBay with no reserve.
Well that's true, it needs more filament current. But they do have a current production substitute now that AVVT doesn't exist anymore. It's the EML320B- XLS.
Best person to ask is at Jacmusic. He might even buy them....

That's obvious otherwise wouldn't be a substitute for the 302B....!!
Still the 320B is not completely identical to 302B.
Both 302B and 320B have the same curves of 300B. They need more filament current which increases their peak current capability. On top of that they have have higher plate dissipation and voltage ratings.
At Va=450V or less and Pa=40W or less they are identical to 300B except filament current.
