As long as we are here, what characteristics should we look for when buying an electrolytic capacitor for output stage cathode bypass use? Both SE and PP. Low ESR? Leakage current? What characteristics make the Nichicon UKA series "audio grade" capacitors (their words not mine)?

Low ESR.
Any capacitor leakage current that is a significant amount versus the output tube's cathode current, should be tossed into the trash can (it is not good for any circuit).
105 Degrees C rated
Capacitors that are not -20% of the capacitance rating, etc.
What makes any part "audio grade"?

Just my opinions

Most seem to measure minus 15% to 20% lately. I'm ready to start assuming when ordering that they all will be minus 20% when tested. I have been matching in pairs.
