I saw someone asked for a schematic on this. This may not be exactly perfect, but I looked up some old info, scoured the pics, and used the posted drawings on the layout to come up with this schematic.
I have not "done" the FET preamp/switching/or 1/2 power circuitry,...there is plently of info otherwise on this site.
Note, I don't believe either description of the loop network was correct. As I believe it is wired, the "network" is only in circuit if the send is used (therefore Ayan's observation that a cable in/out of the loop showed increased highs). Otherwise, the MV to PI connection is made through the tip and switch on the Return jack.
Please let me know if you find errors.
