Radio amp update (speakers that buzz, hum and hiss etc.)

I have made the first amp fix and made some notes.
1. I tried other value capacitors with a higher rating and it worked but there was a pop when starting the radio.
2. Use only the listed rating capacitors and it works fine.
3. You can pull the green capacitors out of there wires with needle nose pliers. Just wiggle the capacitor a bit and then pull them off.
4. Heat up the back side of the board on each existing wire and they come off easily.
5. Try to leave solder in the holes to attach the new capacitors. If all the solder comes out it makes it hard to get the new ones to stick.
6. The problem is fixed if the green can capacitors are replaced.
7. You could attach the new capacitors to the back side of the board which might be easier but you will need to reattach the board a little higher off the speaker to clear the new parts.  There is plenty of room in the enclosure for this.
8. The cost of the parts off Ebay were about $12 to fix all 4 amps.  It takes a little time to do it but saves between $200 to $300 (or more) for new amps.  I'd rather spend that money on something fun, like gas!
