I am looking for a specific CAS 4040 schematic. My creek has sn:9254. There are a lot of schematics only not for mine.
There is schematic on this forum but i can't reed the numbers. And i can't make contact with the uploader.
I need to know witch transistors are being used or witch replacements can be used. I have the folowing (i think):
Q3: ?
Q4: BFR39
Q5: BD139
Q6: BFR39
Q7: BFR79
Q8: BD909
Q9: BD910

I can't believe how many significant variations there are to the schematic with so few production serial numbers between them. I thought this was a very popular product but the numbers tell us it wasn't easy to maintain in production. I agree though, that you'll need at least a better schematic before going further.

Yes, a lot of versions. And i have the one with least info on it...
It seems to be an S1 one version, but a MK2 of it?
