Hello all,
originally i had planned to use an 811A tube for my first ever VTTC. 
I got a cetron on ebay for 17$ and when i attempted to assemble it 
into the circuit, the metal cap on top just popped right off :-( I 
contacted the seller and he agreed to send another. But apparently he 
never sent it as its been weeks now and my apartment complex says 
still nothing from him. I guess it could have been lost in the 
mail(although it was shipped priority mail). So now im in need of a tube.

I was wondering if anyone here has a used one they would be willing 
to sell?Id have to st ick with an 811A tube or similar because my 
filament xfmr is only  rated for 4amps at 12.6volts(I use the center 
tap for 6.3).

Thanks again!
Matt
