If I were to build another Aleph of any flavor I would definitely include Allen Newby's elegant clipping mod. I'm not sure if the mod produces an audible difference, but it's simple and it's an improvement. Unfortunately his web site doesn't want to come up for me. Maybe someone else might have better luck.

yup
later Alephs
agree ; zenner diode is easy to add
if for nothing else , for better sleep certainly
😉
Oh, I guess you're right... I'm so used to the diff. pair being able to be fed from one or both sides... It wouldn't be very hard to add, just 2 resistors. 🙂
6L6 this way?
An externally hosted image should be here but it was not working when we last tested it.
negative input is actualy signal ground. cap is on negative rail, so positive is going to ground.
not exactly
in this position , cap polarity orientation is almost irrelevant
presumably , no DC there

now I'm confused
aren't we talking about question in #48 , ref to sch in #46 , 220uF at inner LTP (negative) input ?
ZM. i think it was the cap in the right lower corner 🙂 no i'm confused too 😀
but on the other hand, it's no longer inportant as the curcuit now is made balanced 🙂

Add additional holes to +/- 25V & GND to accept larger 14/16ga wires. I'm not sure how thick your heatsink plate is, but you might want to try and separate your output mosfet pairs a bit more for thermal spreading purposes. If you have a 3/8" or thicker plate it probably will not matter.
Also slide the 1nf cap near the input LTP to the right or move the 10k resistor to the left.
