Thanks dr! Have been looking for something like this for a while. And the price is right!
1100 pages too !! Wow.
That'll keep you busy for a while

I think the stk-0050 module I designed can be made to work in a sx-580. You will need the 0.22 ohm emitter resistors, same as what the guy did in thread #410 above. bias has to be tested to see if you get the ~35mA.
Always test on the DBT to be safe.
if this works it is way better than the originals. You can use 150W output stage bjts, they are a bit cheaper.
It is summer, lawn mower broke today, need a weld, I would like to simulate the sx-580 design ... but I have no time right now. Another day perhaps.
Made those changes in my sim and got the same resultThat is great Merlyn.
I changed the level for Vin1 to 0.17 which is just below clipping. VR3 to around 110 ohms. So it works fine imo.
Thanks
