Thanks Michael. I thought I give you a try. I have enough for my project, but wanted spares. I will find them, It may take a year on ebay.

I found one NOS Raytheon on ebay, one NOS in obscure tube dealer in FL and another NOS at Tube World. Tube World is usually the most expensive, the Raytheon 6CG7 at Tube World was cheapest of all at $29.95 go figure.

Interesting you also like true Dumont 6CG7. I did tube rolling many years ago and came to same conclusion. Either Raytheon black plate for Dumont works fine.

Because of the .6 amp filament I suspect these tubes will last 25000+ hours.

BTW- I only buy NOS, the used tubes take a beating for some reason with grossly unbalanced sections & low readings.
