All my knowledge and experience are futile value if they went with me one day under the ground, and I have not conveyed to others!

Well said ... 😎
Would you mind if I derived from the calor to make a high power version
"slew" IPS ?
A question ... there seems to be 2 FB loops , one VFA/one CFA.
Does this split any voltage gain between the two stages ?
I was thinking of using a cheap standard dual op-amp , use one for servo ...
one for the main "deal" (amp). Also , standard hawksford as VAS.
OS
That's before first test fire!
I must mention that i haven't all appropriate parts so some parts are for test conditions ONLY.

CALOR GOLD
First test successfully ended.
First time, amplifier tested at +/-24v from two regulated power supplies.
Second test with two transformers ,one +/-16v and other +/-8v in series.
All under control.
All small signal transistors BC550C,560C.
Out fets IRFP240,9240.
Sorry Dr.but i have these on hand now.
Tomorrow i will have a small listening test.
Some pictures from first test.
I guess it is not permissible to show the copper side.

Ok Dr.
Just a clarification. Two transformers are.1)2x16v a.c, 2)2x8v a.c.So the d.c (after rectifiers & series connection) is 2x31v d.c
Terry you can send mail to Dr. ,he will give you everything that is necessary.

Because of such things... read from first post.

It looks almost like good amp...
An externally hosted image should be here but it was not working when we last tested it.
