Yamaha CR-3020 schematic

[kcvintage]

Anyone happen to have a CR-3020 schematic with good resolution? The copy in the AK database is poor and I don't find any online that are much better. TIA.

This is because they are free

If you look for high definition it is not free

Do you have a CR3020 ? Do you have a problem ?

I can't even find one to pay for in high def.

Yes, I have a CR-3020 with two butchered amp PCBs. But I got it for a good price!

Not really... Its the same quality as the rest of the free down loads. Mediocre at best.

Interestingly, Yamaha didn't include the full schematic or wiring diagram in the service manual. There is a schematic in the owners manual (go figure?) but they stripped out the component and other voltages. Thus we are left with the four page document, perhaps included separately (physically) when one bought this beast new, back in the day. All of the copies of the four page document look blurry at any magnification over 200% or so. The wiring diagram is better, and the individual board schematics and component layout diagrams in the service manual are clear.
