I pulled the complete pm5507 manual off the shelf, probably 1966.
No exploded views or dismantling details

thanks for trying!
I'm going to spray the mechanics from outside and hope it will unlock the

removing one (or both) the RF assemblies, but I'd rather avoid doing that.
All the electronics appear mostly OK, probably a lot of the old electrolitics
will need to be replaced.
