I found, in the bottom of a box, over the weekend, an old Heathkit tube amp that my dad built like 30 years ago. He said it wasn't working and the tubes were shot. Well, I got it working again but I need tubes. Apparently, the 6GW8/ECL86 tubes that it takes are not made by anyone anymore and the NOS supplies are running thin. I found a few used on eBay and I'm currently high bidder on one set but I think I will be sniped due to the popularity that these tubes command.
Apparently, they were a tube used in many Heathkit amps.
So what I need help with is finding a place that sells tubes. Antique Electronic Supply is a good source but I'm looking for other sources too. Does anyone have any other sites where I might find tubes and tube stuff?
