** If you were doing instrument amp repairs - you would have come across
the very popular " Roland JC120 " combo amp ( JC = Jazz-Chorus).
Been in production since 1975s and still available with virtually unchanged
appearance.
See:
http://www.rolandus.com/products/productdetails.aspx?ObjectId=249&ParentId=57
Internally, there are at least 10 distinct versions of the JC120, each with
its own schematic.
Only way to know which schem to order is by the serial number on the
particular amp.
Naturally, guitar players falsely imagine they are all just the same.
Just what Roland wants them to think.

It's over 10 years since I got out of doing repairs full time, but now I
remember that Yamaha and others do have different variants of the same
model with the same type number, for different markets.
I withdraw some of my earlier comments.![]()
