came across an old TF46 super cricket the other day and I want to fire it up but I am not sure this is the right charger
do any of you have this tester and if so do I have the right power adapter
thanks

I don't have that unit ; but do have the TF-26 Sencore Transistor testor which is AC only. Though IIRC - the TF46 takes batteries. So I'd estimate the proper charger should output close to the DC equivalent of the battery pile. Next, you'll want to make sure the charger plug has the correct polarity for the receptical on the testor. If lucky, there may be some markings on the unit itself.

thanks for the tip
I think it must not be the right charger ,not only dose the math not come out right but the charger says one voltage on the front and another
on the back
so I just put batterers in the thing and she came right on
already have her listed on ebay
thanks again
