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 ?
