Philips LFH710 transcription machine: service manual wanted

[Bill Woodbridge]

Has anyone ever seen a service manual or schematics for the Philips LFH710 please, or similar?  It's a mini cassette transcription machine for (typically) audio typing work.  There was also a slightly enhanced LFH720 model, and maybe more.

The closest I've got to it is the LFH9750 service manual, which is a solid-state machine made with the same look and feel of the old mini cassette units (so as not to frighten the traditionalists).

Many thanks if anyone can provide a lead ...
