In schematic for my Nad C272 it says adjust bias to 6-7.5mv.
Done,
but cooling fins basically never get any hot. It sounds good but after about 2h playing music it starts to sound much better i think.
My old 216, 214, 218 in the past and other amps i've owned before getting quite hot right away..
Only thing that gets really hot are the 68v regulator and all parts in pre and gainstage (suppose to run i class A so..) but the 4 pairs of Toshiba 1943/ 5200 doesn't really. after many hours of playing music putting the hand om the lid it barely is fingerwarm.
IS it any real danger of adjust higher like say 10 or even 15mv on bias? (my old 216 was biased at 18 i think but other trannies from Sanken)
Anyone experinced from this amp or another with this output trannies? Is the regulator or other parts take a beating if i adjust the bias upwards. Think really there is nothing wrong with the amp. Recapped and done. It was the same before this too.
