Interesting. Thanks, guys, for your insight. I have often wondered if those bleeder resistors could be replaced with zeners. Although I know this was the best the designers could do at the time, the use of those bleeders seems rather inefficient to me (waste of power and heat).

Mondial, just out of curiosity, how would you modify the circuit assuming the original speaker was missing and you needed to use a PM speaker?
