Very true.

I built it with one, two and three k170 and it sounds much better with only one k369

Anyone use the 369 in the DCB1 buffer? Have a sense in that " stupid circuit"?

Cool question (besides the "stupid" quote)

"stupid circuit" are Nick's words, maybe John Curl disagree. Jokes apart, I think it sounds more dinamic,cause the more transconductance ( 40 mS).

No problem using it apart from the higher input capacitance so better make do with 10K pots.

*Don't remember the quote but I should have used stupid in the sense of stupidly simple.

Maybe we could use those also in the output buffer of the folded.... More dynamics you say.... I like the idea

They are more useful in very low input signal duty but if having spares its alright. Got to keep about same voltage headroom across the output stage buffer as was with the K170s. If higher idss, as usual with most 369BL, the R in the rail's last RC must become smaller. Also, by using the oscope, make sure it does not react on output interconnects due to the higher Yfs.
