I have an old Tek current probe with amplifier that needs TLC.  It works but the waveform isn't right.  I think the problem is in the jaws of the sliding part.

I'd sell it to someone who'd try to fix it.

 Hi Charlie..a low cost low frequency solution is DIY converter a low cost AC Clamp ammeter,

Just remove all..and put suitable magnetic wire turn, terminated in low value bladder resistor in a bnc connector.

Use the minimum possible  turn/bladder R, suitable for good low frequency limit's.

Perhaps will  work well to 20Khz or more.

The diameter of the clamps is proportional to the current to measure..the original range will give you a good idea about.

As an alternative to a current probe, you can probably get by with a low value
series resistor and differential probe.

Or, if you have one of the two components of this probe system, I would be interested in that as well. As a third option, I could make do with a Tektronix P6021 probe with the passive terminator.
