The 6528 double triode is the same kind of family as 6080, 5998 and 6AS7. Good sounding and a simple push-pull solution in one bottle. Low plate resistance of 250 ohms
Morgan Jones used it in one of his amps in "Valve Amplifiers" so information and schematic there.
I have six of these. They test good as well.
Looking for offers on pairs or all six.
