I would absolutely LOVE to have that Heathkit unit!! Well kept vintage test equipment is about as neat as the radios and TVs we work on!

Hi Tubejunke ,
If at all possible to find one reasonably priced , you would gain a great test instrument by obtaining one of these . The one I showed is the C2 model which is in between the entry level CT1 and the top end model C3 . Any of these with the eye tube and a "leakage" function of testing are the ones you would want since they put a real 450 Volts DC on the cap under test . The really great thing about the C2 is that it only contained 5 capacitors and the recap of it cost less than doing a typical AA5 . It's a neat circuit in that it only uses two tubes , one is a rectifier and one is the eye tube itself . There are two 450 volt 8 MF electrolytics in a voltage doubler arraingement that take the rectified 220 VDC from the rectifier and turn it into the 450 V for the test .
Since it's such a handy instrument I use it to check all the caps coming out of , and going into , any tube equipment I work on just for kicks and grins . So far , I have found a few brand new caps that failed the test and lots of old used ones had leakage values deemed unacceptable .
Have a great day and Happy Restoring .
