The Fine Things are Always Hand Made
The service manual I got from Alan Jesperson includes a very good copy of the schematic. It is for the 7 knob version. The only apparent difference is the switch that allows you to go from radio to phonograph.
This manual covers all the service info including alignment.
Alan, I think, is on this list.
I seem to be having some trouble getting ahold of him, I have emailed him twice now with no responce. I will try phoning tomorrow.
