My Tek 130 had several Sprague Black Beauty capacitors in the oscillator

All were bad. I've had enough trouble (and been shocked enough) with these
caps
that I replace them on sight.

Have you checked the smoothing capacitor on the power supply? Mine was

Is there anyone familiar with this unit? I have one that isn't working

and have traced the problem

to
the variable oscillator not oscillating.
