112 RD50 distortion

Severe distortion at all volume levels traced to short circuit Zener D9 in bias circuit causing R62 to go open circuit. Sounds great now.

Seems to be a common failure point for these amps, I've only seen a few operational RD50s that still had their original zener and resistor intact.
