I know this has been asked here before but
I am looking for the owners manual for the
old Kenwood (Trio) QR-666. I bought this
unit new in the early 70's and have just
dug it out of storage. Need the schematic
as well as the alignment procedure. Photo
copy will do and I will pay any cost involved.

It's only a guess, but I think the R300 manual would work too.
