Tokin it to the next level!
Yup, as ZM says, that looks like the baf 2015 amp without the trafo. Very cool indeed!
ra7 meant input xformer, as way of Schade-ing MOS iteration of BAF 2015 amp
anyhow, as I said - anyone think - ACA - SIT variation?
all I can think now is - how small NFB amount is, I can imagine Papa's wicked green adding that as a sprinkle
I was close enough. How low can you go on these load lines on the Tokins to still get nice triode behavior and lower dissipated power? Is a 5W 'summer setting' possible? So far the best summer amp in my system is the mini ACA.it says 180W of heat, both channels/case
that's one small Burning Amp, be sure of it
easy enough to investigate, with handful of parts
better to have that fun, instead of watching TV, for instance
I mean, we can draw general figures........ 20V Uds, 1A Iq......... but each of us is most likely having different needs and certainly different taste and criteria what's acceptable
again, easy enough

so, Greedy Boyz, you got it at BAF 2015
now buffered and de-rated for FW casework
anyway, be happy, Papastash of elevator parts is low 5 figures
edit: anyone seeing SIT ACA there?
imagine buying two SIT-4 and bridging them
Hmm, can we bridge the SissySIT 4.2? How much power would that do?
DC current or AC current? The DC current is a function of DC voltage on the gate. The AC current is a function of dv/dt and input capacitance. AC current I=C*(dv/dt). The higher that dv/dt is, the higher AC current is.
and lose that 2nd dominant magic?
please, we all know how good THD Generator Sissy is, why spoil that?
that's "simplified circuit"
see as example, ACA simplified circuit, Article page 4/10

I remember that room last year and enjoyed talking with the guy about his Beast amp. The amps looked like little waste baskets from the 70s, though attractive.
Are CUBE speakers the ones that were called Plex-i-Box last year? There were some plastic boxes you could get with different full-range HE drivers. They sounded good. I miss not going this year.
and remember, SIT being depletion mode part ( gate needing to be lower than source, voltage level wise) there must be few funny quirks or two, in full schematic
somehow I have a feeling that quirks are already shown by Pa here
That simplified schematic looks like a ACA with a SIT and GNFB to me. Surely a good recipe. Maybe there are some new tricks in the control of the top FET?
besides fine tuning of ratio of resistors in Mu Follower, I see no reason for any "new tricks"
simple and functional, who can ask for more?

Open it up, send send us the pictures.
As a true diy nerd i always find the guts of the amp easily x10 more intresting than the shiny box that hides all the inside build and electronics that sonically, actually in the end really counts.
As always as we say about the amp builds here: Pictures In focus and well lit. With dead bugs and all 🙂
