I test the capacitors normally with a Amtron Capacitor tester that I got for a Christmas present as a boy in the early 70s. I also have a Peak tester.
John the resistance is measuring 74ohm. I think I have now got it about right.
I'm feeding about 11.5 volts at about 190ma .just checked it now and it's warm but not hot.
