that diode is suppose to go across the motor leads to suppress back
EMF which can damage components..
It would be a simply low current SI diode.

In which case putting in something bigger like a 1N400x ot UF400x if it has
to be a fast device would do no harm.

I've known 'back emf diodes' like the 1N4148 to be 'killed' by even modest
size relays. I never 'cut corners' on that component any more. 1N400x every
time.

The anode of the diode is attached directly to three of the resistors
as shown.

I have tried to re-create the circuit board traces on the other side.

The cathode connects to what N_Cook has described as an inductor.

Take a look at this photo:

Thanks to everyone for your help so far.

Can you not trace out the whole circuit ? There's precious little there.

Well, it has all become academic at this point.

I ran the motor off of a 9v battery while it was hooked up to my
multimeter's current setting.

The motor was pulling just over ONE AMP of current!

I took apart the casing and studied everything....sure enough, one of
the armature windings has a scorched spot.

This motor has gone to that Great Cassette Deck in the Sky....

You could have re-wound the motor! :)

Yeah, I know...but I'm just too lazy! :)

There are replacement motors available from MCM and the like...

12V CCW, 12VCW, etc.

Standard mounting holes.

Usually pretty easy to wire in place of the original.
