Thanks !
I thought the choke is going to be marginal in 160H/15mA configuration since I don't know how conservatively they are rated. It's worth to try.
Yes , some form of input gain stage will be incorporated. Either Step-up 1:2 IT or just a single triode something akin to Larry Moore 6j5/VT10/300B design.
Best, W

Using a siemens Ba 'Post' tube as voltage stage for this topology and go for full DHT setup.
These are truly marvelous. I use a 90K plate resistor, so you need some B+.
Run them at 3ma. Their life expactancy is extremely long.

Thank you NC. :)BUT
All my projects are usually stopped at some point because of "paralysis by analysis" and the desire to make it better. In consequence, I could have a nice, satisfying factory system playing music but of course I've blown the budget on the parts and " different directions" and listen to a "temporary" dreck for last 8 years (or is it 15 already ;?) this GOT TO STOP !! ;0)
I think I will use humble 5687 or even 6j5 for now. AN is using single 6J5 driving parallel 300B in $50k Kegon and people are ecstatic ..pSSS .don't tell anybody else about those german tubes ,they are expensive enough ....
