  • Many thanks goes out to Merrylander for showing me tricks and saving me lots of time getting to the root of my problems on my Yamaha CR-2020.I had read his threads before to get familiar with this receiver..that paid off...then after a few tips from him I was well on my way..what fun to have such a beauty come back and sing like like she was meant to. Had no protect circuit, no sound (headph. or speak.outpt)Only two lamps and leds were ok..meter swinging left..pwr supp. shot ...new caps(not all just any that would read inf.or less than the normal + or - %..16 caps replaced on power brd..two backwards.. oops..and replaced the 234's with nte54's... on to right channel output transistors...still no protect circuit ,till I changed polarity on those two caps ..duh.now protect circuit ok and nothing but sweet sounds..then to the lamps..also check the one on cleaning the glue from the vent holes around t712 and t715..thanks again Merrylander you are the best...!!!!!!!
