6bm8 / Ecl82 Pse & Srpp

Haven’t seen so many 6BM8 / ECL82 PSE or SRPP designs around a net. Am I been blind? 😎 So far have found only one schematic of each configuration. What’s the reason ? :scratch1: -diminishing returns using two valves instead of one, increased PS requirements, difficulties to find a suitable OPT, or sonic degradation by paralleling or cascading the stages.
If it is so popular tube (read - good sounding) why there is not more topologies tried out besides SE and PP? 😕

In my opinion it is not a good tube... better a 12AU7 and a EL84 that's pretty equivalent... I'm using that tube in a one-tube regen radio... just for fun.

And I seem I cannot find a good NOS one... here I can find only cheap Philips Miniwatt salvaged from TV audio output stages...
 
Hi there........6BM8's ECL82's are excellent tubes...esp config as triodes..I use em' as drivers for parallel output hi power p-p o/p stages. I've tried many other ECL types and these offer the lowest distortion in intermediate stages.
