See first post and schematic. It lists Cinemag CMOQ-4LPC as an option (in fact there are many options).
Best,
Anand.
Thanks Anand, but somebody had some issue with some transformer and I can't find the post.
Add: I have it, the issue was with an Edcor in another amp.
Solved
Yup
typing from phone so lazy to check - I believe you have 4 types of xformerd noted on sch
you lose supersymmetry

little daughterboard made from one simple reason - for some time it was impossible to find LT3092 in biggest or mid sized case, and I was reluctant to chase smallest one
thus I tried and found option with LM334
as you can see in datasheet .......... and I did use few tricks more collected from clever ppl, schm I'm using is to achieve best possible TempCo
in short - transistor is not cascode but part ensuring that minuscule/just enough current is going through LM itself, while 1N457 is there to have exactly opposite TempCo
it'll never be as good as with LT3092, but taking context in account (entire amp circuit and drekload of other TempCo involved), practically both solutions are in same quality bracket
so, leave daughterboard as is, whatever packed in small bag - it'll work

I'm getting a touch of audio nervosa & could use some reassurance.
The SIT implementation of the Babelfish M25 / SET uses an IRF510 MOSFET to drive the gate of the SIT. Fine, I had a few in my junk box. They test out fine with Vth in the 3.2-3.4 range, but they look old and funky and they are in the dang signal path. Should I have some fancier parts here?

looking good to me
you could avoid half of complications, if not all, just if you did say that you want to build SissySIT, while ordering Babelfish M25 boards
anyway, don't despair, even I'm more than lost in all amps I made in last few years
whatever, last bling in that field is SissySIT (42) ..... which you'll have in the end, with slightly different boards
