http://www.ebay.com/itm/271159333638?ss ... 1423.l2649 Has anyone tried these 300B's .
I have a pair of UTC LS-58 output transformer I want to use , they are 2500 ohm PP , and was figuring about 380 volts B+

CG-429 power transformers
LS-58 outputs

LS39 input transformer same as LS-12 only 100K secondary

RH8250 filter chokes , ran out of UTC's .

Any sujestions on the best tube to drive 300B's

Nope, but there's a bit of a description backing up the claims:

Any sujestions on the best tube to drive 300B's

Anything that can swing cleanly 120V+

I like using lowish grid leaks on them (47K) and driving them with mu-followers or mu-stages.

Single-ended you can use a nice video-output tube or even a 6SN7 if you've got some B+ to spare.

Cheers!

I bought a pair of these for my 300B SE amp and compared to the EH 300Bs they were bright with a bit more hum (AC filaments). With my dimished higher frequency hearing they were ok though...lol.

I plan on DC filaments , so hum shouldn't be a factor ,but getting enough drive does .

If you use CCS DC heating, I have a nice circuit/protector here:

I just happen to have four of your DC filament circuit card's , I might be all set .Now only if I could find some driver transformers that have the same band width as my input and output transformers , without having to pay $600 for a pair .
