Hi! I have recently acquired a CA 2010, and want to change the output transistors, can anyone please help with the model nos of the transistors that should go in?
Thank you!Hi, MJ21193's and MJ21194's are what l used.
Hi, why change the outputs? Are the old Sankens defective?Hi! I have recently acquired a CA 2010, and want to change the output transistors, can anyone please help with the model nos of the transistors that should go in?

When I switch on the amp and start playing music, the sound from the right channel is all ok for 5 mins...then after 5 mins the sound starts distorting suddenly and then starts dying away...This happens every single time I switch on the amp..kinda repeatative.Hi, why change the outputs? Are the old Sankens defective?
Thank you! Very happy to meet you guys!!Welcome to AK...
Can't be the outputs. Don't change them.Thank you! Very happy to meet you guys!!
Suggest you also change the vd-1212diodes in these which are known to fail as preventative maintenance
Not..Actually the VD1212's get a bad rap. MV-12's were more prone to failure. I've only once found a bad 1212 in the last 10 years( 50 or so yamaha's) It was in a C-4 and it was causing intermittent popping. ie noisy.Suggest you also change the vd-1212diodes in these which are known to fail as preventative maintenance
Might as well replace the class A relay as well. It requires the same relay as the protect relay.
