Yamaha CR-1020.. replacement resistors and transistors help needed.

Register to hide this ad
Thanks for the recommendation with regard to the diode choice. Much appreciated!
With regard to the resistors unfortunately I'm not in a position to take out the amp boards at the moment to read the markings. (And do those 'IP47' resistors have bands?) Ideally, though I'd like to get the order started as delivery to the UK takes a little while.
With transistors my understanding is that not all 'equivalents' are equally ideal in a particular location, hence if an experienced AKer can thoroughly recommend the best current replacements I'm happier taking their personal advice. Thanks again.
 
All KS~ prefix devices are available at Mouser. I do not have the outputs in my dictionary someone else will have to suggest subs for those. LittleDiode does stock all of the originals if you want to go that route. Example the outputs 2SB555 LittleDiode | 2sd425 LittleDiode but ouch $$$

and those transistors... for example, just search "2sc734 equivalent" on google
why using the transistor choosen by Google ?? Google knows everything ??

What is the reason for replacing those transistors ? Yes ! I am like you , why ? I will be curious to know the reason

Replacing all these transistors if they are good is silly and at your place I will use original and not other

Don't tell me they are obsolete !
 
Thanks Eizner. A great help.
And don’t worry, I won’t replace any working tranis!

Might you know which replacement I might need for R627 and R628?
