forgot to mention the bit version is with SK170. Maybe the OLG is much higher than with the J113.....
everything is in here https://www.firstwatt.com/pdf/art_diy_opamp.pdf
as Pa is not going to give ya that soon, someone could clean Stasis FE and post

pinout for 2SK170, 2SK370, LSK 170, 2SK2145J113 - manage, isolator bushing on one pin is solving rotation of same, if needed
same applies if you want to use BC639/40 instead of ZTX
depending of rails voltage, resistor or two needs change of value, trivial

Ha! No, I was just trying to understand the schematic. Is your ‘-IN’ part of a differential signal, or is it just ‘audio GND’ for lack of a better term? I admit this is rudimentary stuff on my part…someone's greedy?

same as screenshot of Papa's schematic in #88, this is having positive input, negative input, input GND, SE output (in phase with positive input) and output GND
so, SE/BAL input, SE out
dual rails
making it for single rail is trivial, but I'm leaving Pa to proceed with limitless overindulge of Greedy Boyz
tomorrow someone will ask for A Class amp with Solar PSU, 100W/ch, complete stereo kit for 100$, Canadian
