I found CA1000 and CA2010. Maybe of some use ? With Google I found this : 90 watts @ 8 ohms AB /20 watts Class A

Samebody has got a techincal manual of this amplifier?
I have problems with one of a friend. It has the two tranny burned on each channel. I changed the bjt 2sc1079 with a mj15015 and the 2sa679 with a mj15016.
Now the ampli works but only the 15015 is biased at about 180 mA (85mV on 0.47 hom emitter resistor) while only 0.7 mV on the 15016. This on both channel. So when the 180 mA on the load of 1 bjt are finisched the sound start to be distorted.
Could somebady give me some help pleace?
Ciao.
