Output transistor recommendations for Yamaha CA-1000 MKII - how many needed

[eldarvanyar]

Hi,

I have a CA-1000 MkII in the UK and would like to overhaul it

Can anyone tell me how many transistors are needed and which ones to go for?

Reading a previous thread someone had used
Onsemi MJ21194G and MJ21193G (250w)
MJ15015G and MJ15016G (180w)

Thanks

Onsemi MJ21194G and MJ21193G

2 of each total for both channels.

Don't know how to use a service manual?

Avionic, you are quite right, I have just downloaded the appropriate service manual

Thanks really appreciate it. It would be good to keep this amp going for many years to come

Would this be worth purchasing? Its a kit with all the capacitors

That's probably close to what it would cost with shipping from Mouser or Digikey. I'd think about replacing the two " class A " snap action switches and the protect relay as well.
