From time to time i throw a look to check the work in progress, and if i can give an advice it is to replace the OS dual pair + drivers by a single BDV64/65 darlington pair, it s as fast as the BD203/204 + BD235/236 configuration and it hold theorically 125W TDP per transistor, of course some Sanken darlingtons would be much better but they are not cheap, not counting that some of their best parts were obsoleted for some reasons.
The two CCS for the diamond buffer should be set at something like 5-6mA at least even if you keep the OS as it is.
Last but no least a dual differential IPS is by far a better solution than the quite original one, with some care you can approach
the perfs of a classic blameless with the advantage of a true symmetrical driving stage that work flawlessly.
Anyway good luck with the remaining efforts and keep on the good work.

By September at the latest, I will have the time I need to pursue the 25W-Krill project further.

Just a quick thought:
shouldn't it be quite sufficient if the base-base resistor shown in principle with its 8k85 ohms consists of a small compensating network with an NTC?
Just a first thought to resume the project 25W-Krill.
With pleasure,
I consider the concept and principle of KRILL to be absolutely trend-setting.

Why was this user banned? Their combination of utter cluelessness and inflated and ego is hilarious! I’ve been chuckling over this thread all morning.
I could not disagree more. This amp takes 3 adj trimpots and with gain of <0dB requires very high input level making things complicated.
