What driver tubes are you considering?
Are you looking at direct coupling?
I have a Bottlehead Stereomour with a 3B7 driver that is my go to amp. Love the music it makes.
The Tube Audio Labs 2A3 currently in the Man Cave system uses either a 6C6 or 310A (toggle switch to select either 6V or 10V respectively).
In my opinion, I think it sounds wonderful. I would give a slight nod to the 310A but both drivers sound good.
.....but I like to be contrary.
It was new to me. Thanks for posting the link.Speaking of Dr./Prof. Jean-Michel Le Cléac’h, I just now stumbled across this, and thought it cool enough to share.
My apologies if everyone knew of this but me

Question for @shoshin
I have a 2A3 monkey circuit amp
2A3
Plate- 460Vdc
Cathode- 216.5
Grid-172.5
243.5 V p-k
-44 V g-k
Will 172.5 Vdc on the plate of the EML 20B work?
How would you recommend biasing the 20B?
Thanks
Robert
I certainly think that most horns sound (much) better when not used within an octave or so of their cutoff. Not sure if I'd qualify the audible issues that result from noncompliance with that advice as honkiness, though.
Of course, I am currently violating that "octave above cutoff" dictum, but I like to be contrary.
Currently running the EMILARs (with JBL 2441 drivers) first order at ca. 600 Hz nominal XO -- apostasy
There's interesting chatter going on elsewhere about modern high-end horns -- I am just increasingly bewildered by the complexity of the whole subject. Maybe I'll get me some vintage 4" radio shack cone MRs and some 2" cone tweeters with chrome dustcaps & be done with it
Thanks for the replyMost DHTs are pretty flexible, but I reckon that might be pushing it. Drawing roughly 10mA, would put the grid at -2V relative to cathode: not the most linear part of the curves and (not having calced it) the gain might suffer. It could "work", but it would not be ideal... probably no better than what you already have.
Thanks for the reply
“would not be ideal “ is a accurate description of my system, but I like it.
