Apology if this has been asked before; my googling skills to find such fail me.

I am looking for the Va -I(a+g2) datasheet showing 6L6 in ultra-linear operation, if someone could kindly give a reference. Such does exist but are scarce, unable to locate myself.

Thanks!

FWIW, i recently built an JJ 6L6GC ultralinear amp running on B+ of just 350 volts dc,
it sounded fabulous to my ears, 500 ohm cathode bias resistors on each cathodes with a 470 ufd 50c ecaps,

Rayma,

Much obliged - the Audiomatica graphs are the ones I am missing. (How did they not come up in my recent search ...... 🙁 )

AJT,

Ah yes; the good looking JJ tubes. EH also has the same appearance. Thanks for the photos! (Ltp type phase invertor/drivers?)
