I have such a great experience modifying my 555 (s) that I can't help but think that a cascode SK170 SJ74's push pull on the front end of this BJT amp would be oh so sweet. I just love my modified hafer jfet amps and want to have the same love for the BJT Adcom amps. I'm not going to go into the weeds here about the engineering details. My hope would be that this community might help to educate me as to why I cannot use a F5T FE to drive an Adcom 555 output stage. I happen to have a surplus of these board so that I can get enough output pcbs to realize 6 pairs. I do realize there is no feedback circuit, but what else am I missing beyond using ohms law to adjust voltages and current ? I suppose I am more keen on understanding these circuits than anything else.... Does the F5t FE rely on the precision output stage so as not to require a feed back circuit? For me, I have to say it seems like Mr. Pass gives enough of the goods inspire the drive to want to learn more. Peace.
we all are mostly self taught Paesanos around, so nicely prepared and enclosed set of original schematics, and ( why not?) proposal/graphical presentation of your idea, would help immensely**

Just replace the output FETs with BJTs.
This is of course only the topology.
You need to work out the details yourself.
