Stereo probably works but not the TT.
Set looks like the early SS chassis.
If so it probably dont need much. Chassis was modular
with an upright mother board. Design is strait forward,
easy to understand & fix much like most early SS sets.
Gave a nice pix, I liked working on them.
One thing on all Maggies of this era is to resolder all the
mother board & the modules where the plugs are.
