In Reply to: Suggestions for drivers and OPT's for 10Y and/or 50 output tubes. posted by Rick R on March 30, 2007 at 12:20:57:
I know that jub jugs will tell you to use the 46. I haven't personally tried this, but he's very enthusiastic about it.The 31 might be a good contender - very nice sound. Some other DHTs with more robust characteristics for drivers include 71A and maybe 26 or 12A.

...what can I say, I think it's great!
I'll agree... It makes a wonderful driver.
Could you describe the heater supply and op. points you like for the 46?
Usually I run at 25mA/250V or so. For heaters, I would definitely go with DC filaments for use as a driver. Some sort of CCS type supply, e.g. Tentlabs/Ronan-reg., etc. is best. Preferrably, choke load or transformer couple.
Where are these filament current regulators available (or where can I find the schematics)?
for driving 45, 2A3, 300B, etc.I tend to prefer the 801 or globe 10 to the 10Y. They also work well for linestage duties.
