after you finish playing ...... observe startup and temp behavior , at least in simulator
after that , in vivo ....... I'm glad that in vivo , things are even better than sim. prediction, judging by experience with Sissy and Babelfish M25

Sorry to disappoint, the big SITs are just beyond my budget, I am working on a hybrid using regular IRFP240 and remember you guys so I drew up the schematic and sim it as a gift. Current in progress project is as attached.

The topology allows use of SITs that won't bias correctly with the M2 opto bias, but bias becomes dependent on Vbe of the pnp.
yup, no free sonic , or any other lunch
speaking of lunch - having some kwayzee name for your intended Enterprise ?
🙂
edit: while we are at that , Bob is also sending his greens and greets

I worship Papa for introducing me to the excellent A40, my first diy build during my college days. Decades later Srajan and Sakuma poisoned my sonic digestive system real bad. So my work will be mostly a sprinkling combo of Pass & fanz inspired ideas with direct heated critters. To honor you and Mr. MR, I will try to include at least a piece of iron part in my designs. Still has no thought about any name and the plan is only to contribute a little bit to the diy audio community. 🙂
Remember the problem with the beasties? I think Pa just handed out the remedy in the genuine article thread, use beefier 8 legged opto, the 6n type, instead of 3n veggies. 😀
