Marshall T65 and its compliment T64A (curiously one suffixed A
only),
TOP66 package Motorola MJF 22 , also marked R91, TO220 package, not
found
on
Motorola site

TOP66 ? Do you mean TO-220 ?

Resistors in TO-220 packages are not unknown. Possibly low inductance
low
ohms type. What's the function - and marking ?

The package that plastic 2N3055 come in like TIP3055, probably something
like Marshall badged TIP3055/TIP2955 output pair

Oddball devices.

My big Motorola Power Devices manual lists nothing like it ! The MJFs have
fully
isolated packages btw. Is that the case here ?

It was actually MJF122, the centre spine of the retaining clip had messed
up the surface of the package and obscured the 1 , so plenty of info on that
one
