Ask The Tech: Modifications:TalkBack
Then scroll down till you see the Post "Talk back" on 09/02 02:55pm from 307 and your question will be answered.
Put a 15 to 50 ohm resistor on the main board connecting the Speaker Output jack (center) to chassis ground. As for the noise , sounds like a loose solder joint , unfortunatly it could be anywhere.
There is a lot more information there to help you.
Hope this helps
