What differs it, in layman terms, from the Zv7-T. What have you added, changed and why?

......
even if term "designing" is arguable when I'm in question , in this case was more redesigning ;

Magura sez - "see what's possible with my SUSY circ" , I said - "there is no SUSY in your circ", he said "you liar and cheating weasel " , I said "utatautata!" , he said " OK - draw , but only with parts I already have in drawer... don't want to chase those sissy parts you all are using "

these days I'm drawing circs in same way - using leftovers of my head , but lately using LTSpice for checking , instead of just gray cells and time on bench ; that way I upped functionality right from the paper , for few percents ...... circs are more and more complex ( trying to leave less and less active parts )

thought - search here for Semisouth Donuts thread ; there I drew few more circs , but I didn't check them in sim ( meaning on servo functionality )

Thanks Massa

Thats what I thought by getting a lic degree on reading those threads. I linked to the Semisouth Donuts thread a few posts back, havent plewed it yet tho.

I have practically none of the transistors at home, so I would need sumthing that is doable to make a Europe Mouser BOM on (ie preferably not outdated three legged critters etc).

Gonna eat the Semisouth thread to the coffee, then try out some BOMs

Two 3kVA doppfel-choky and ditto 300 VA 18+9 V is ordered now, so I better hang on to this

yup

that's that thread

whatever - I drew schmtc in Eagle , so that's the reason why is so nice

it never came to bench , where I needed to confirm servo functionality

so - if ya wanna play - be my guest - and take all credits for your self

I can't promise that I'm going to try it , even only in sim - too much chores these days

so - make an amalgam of ZV7 , Magura's , and these two - it's simple

aha - I owe ya this answer - these days , tnx to bad influence , I'm somewhat more in thinking of SE

bad influence picture enclosed

you can go with IRFP first , then substitute with SS Dodos

entire shebang is biased by central CCS , so no biggie - put whatever you want
