sorry to revive a 2 year old thread but we at the shop I work at came across one of these yesterday that needs repair. r23 exploded and we cannot read the resistor value. If any one has a schematic they can email or can just tell me the resistor value for r23. We would be greatly thankful.
email me at dunomynaim79@comcast.net
