It was a "smart trick"
it hides the basic sound quality of the incredeble poor schematics......its called "floating ground"
Musical Fidelity used "floating ground" as well for there P270 and A370
Removed my comments on Krell engineering or lack of same
Should not spoile your fun

Hi all,
I have now drawn the KSA-50 mk.II schematic in my CAD software: http://www.delta-audio.com/temp_acd/Krell-Clone_KSA-50.pdf
Please let me know your comments before I start the PCB-layout
To PMik:
I agree, however we do diy for fun

Jan, it must to stay Krell, not to be DuDu ( Dupont - Dudek ) , so only little notices : Q 105 - MPSA 92, Q 106 - MPSA 42 - Pc in this position is not big, so there is 0,5 W Pc enough ( MPSA .. or MPSW .. family ). Q 111 - give there some transistor in TO 126 ML ( full insulated - easy mounting ), such as 2 SC 3955 or similar. C 109 - give bigger value ( cca M1 - 1 M / 63 V). Current sense ( R 301, 302 ) is better to lead from both emiters of power devices ( value 4*200 R ). Give on rails blocking capacity ( + to G, - to G and + to - ). Other improvement are not required, 'cos Daniel d' Agostino is boss .
