why? i ignore his calculations and not make it my problem...
if you can not understand the design to begin with, then everything is off the table, I will never whack my head about it...

It seems that you know what to do... I suggest looking at the actual schematics in question first.... that might be the starting point?
Did you miss my post where I clearly stated that you overlooked the fact... that the choke in question supplies the full current grunt needed by the amplifier PCBs? I even posted a little photo...
no, i saw what you posted, but i have a different idea, i have seen so many different Japanese design's from repairing Japanese amps in the 80's that are similar to this Marantz, so it will be useless to argue with you about what you are talking about...sorry, i will not slug it out with you, waste of time...
Based on what? Your experience?? Did yous see the size of that choke?? Drawing from your experience, do you think Marantz would use it just for the pre-amp section??
Woah... Impressive! Did you bother to look at their schematics?
Of course, it would be useless... you did not bother to check the circuit diagram, went on showing here how you are experienced and know so much, and then admitted the choke calculations are correct... for a pre-amp section - which is WRONG.
Haha... but YOU contributed as well in a thread.... ah the lengths you're prepared to go to... just to avoid acknowledging that you were wrong, like - completely. And your experience did not help... like a single bit.
i was wrong about you....i thought you know...look at post #32 was trying to say that from my posts...
i am out of here....
the choke is most likely steel cored, EI most likely, i designed such chokes, just because the can is round does not mean it is a toroid...
Looks like R803,R804 are 1R, 1/2W. That puts some limit on what the current through the choke is likely to be. BTW, have a pair of those power amps here. Haven't gotten around to opening them up to look inside yet, though. SQ is very good. Better in some ways than Benchmark AHB2.
