The schematic says current draw is 19-24ma, battery life 130-150 hours, that's for both A & B series... I'd guess a modern alkaline battery should come close to that...
My White P808 draws around 17ma and plays quite well, the other two are only drawing 6-8ma and are sorely lacking performance... None have been recapped and as I won't be playing them, likely never will be...
Here's the schematic for A series, apparently only version to use a conventional speaker, B has a pin speaker...
BTW I've seen magnets on the pin speakers disintegrate, apparently acidic vapors from battery leakage destroys them...
