Here's this odd transistor only marking on it is:
ADY26
From web search, it is TO3 package. Felt like
solid tin
plated copper w/ bolt stud.
What it is usually used in what equipment?
What era that transistors were used? 1960's?
This one is way before MY TIME. :-( )

Bolt stud?? sounds like a TO36 . . looks like a big round doorknob with
emitter and base leads in a straight line with the stud
(case=collector). Most of that case style were PNP germanium
transistors, used in car radio output stages, and some old two-way radio
T-power B+ supplies. Being Ge, they usually weren't too reliable, and
quite prone to failure.
