[Test-Equipment] Simpson 269 Series III

[Barry]

Picked up the 269 Series III today.  Everything works and it is in great shape.  Came with the leads with the alligator adapters to boot.  The plastic handles had broken where the probe tip presses in but that's an easy repair.

I also scored a Triplett 310 with the Model 10 AC clamp and Model 101 adapter/multiplier all in the tall leather case.  I thought I had both leads but somehow one of those either got away from me or I imagined both.  In any case, the one I have is in pretty poor condition and I'm looking for new leads.  Anyone know if what is now known as mini-banana plugs are correct for this meter?  If so, I should be able to fashion some new leads with some replacements.  BTW, the 310 appears to work in all modes I tested including the AC clamp.

Thanks,
Barry - N4BUQ
