That's $99.95 for a matched pair. So, just less than $50 apiece. But they do seem to be going up. Seems like everything is.
Regards,

Duh...
Dunno how i missed that.
Whew.. what a relief!
They are up some, however...
I'd checked a few other sites and that one was
just an example.
Sorry.

And yeah Ed... Everything IS up..
Just have a look in the supermarket.
PS: Thanks for the tip Gregg.

less is more AKA the "brick bomber" project
Posted: Mon Jul 14, 2008 12:06 pmThe US Dollarette is down in value as compared to the Euro, Ruble, Dungoon, Zloty, etc "foreign" currency, add in the ever spiralling cost of "go-juice" and everything has gone up (except for incomes)... Yellow_Light_Colorz_PDT_21
I've tried some of the 1950-1960's vintage Russian 6C4Cs from "sovcomm" on e-bay, these are more like a clone of the "old-school" 6B4Gs, with the two paralleled smaller triodes inside the tube.
They're less costly than the "modern" manufacture 6B4Gs, but they are also less rugged, the max (15 W PD) voltage and plate current ratings (250V P-F and 60 mA) should never be exceeded, and should be treated with the same care and delicacy as vintage RCAs or Ken-Rads... They are perfectly OK in the G*S*G circuit, I've used them wioth great results. The P-F voltage is a tad higher, but then the plate current is commensurately low enough to stay within the "safety envelope"
FWIW, these 6C4Cs were a result of the Soviets building their Tupelov TU-4 clone of our B-29s, after WWII, they had four of them that our pilots were allowed to fly in to Vladivostok for emergency landings after doing their missions ofver Japan. Russia was officially "neutral" in regards to Japan until after VJ day, when they then declared hostilities on Japan.
Stalin's orders were to copy the US design, and not to improve upon it. The only thing that they had difficulty duplicating was the large tires in teh landing gear, and they found a way around that - they purchased out surplus "land train" tires which were used in the Arctic and northern Canada during and after WWII.
The newer single-plate 6B4Gs and 2A3s are a lot more rugged, with the J/J 2A3-40 being the "alpha male" of the pack, as they are essentially 300Bs with a 2.5V filament, and the 300B's 40W plate dissipation rating. .
