Looking for Concertone Series 90 or Teac R-310 Schematic

Like the title says. I have a Concertone 91 module which is the same as the early version of the Teac R-310 electronics (I believe the module was RA-12 or AR-12?). The Teac schematic is posted on tapeheads.net, but I am awaiting approval from a moderator to join that site. Thanks, Mike
