<The original transistor has the following markings :
<
<Ti (Texas Instruments Logo)
<SWC0166

HP/TI house number doesn't cross in any of my books and I have a pile of
them(some very old).

<6934A (Date code, I think).

Most likely.

<It's in a TO5 can, and is certainly NPN.

There lie the next questions:

        SIlicone or GErmainium? (makes a difference)
        What is the collector to emitter voltage in circuit?
        What is the base/emitter voltage for the ON case and OFF case?
        How much current does it handle in circuit?
