Fender Princeton Chorus - Bad Static and Thunder

[earache]

This 1999 Fender Princeton Chorus SS amp I have has BAD static noises occasionally. It only affects the right speaker, but boy does it jump when the static is happening! I currently have it open and powered up and when I poke at the components around the spade lugs on the board where the right speaker is attached, I can usually provoke it into making the noise. I have swapped the left and right speaker connections and it doesn't follow the speaker. I thought for sure that it was a bad 150 ohm sandstone resistor (R116) which is right next to the spade lugs for the speaker, but replacing it only helped marginally. I have touched a hot soldering iron to all of the points on the board around the speaker connection but this didn't fix the problem. I suppose that it could be any or all of the components around that part of the board, including the 9 pin TDA1514A chip. Do these amps have a history of bad components/soldering or both? Has anybody any experience with this amp and/or have suggested fixes?

Did you apply fresh solder with flux when you touched a hot soldering iron to those points?

Good news! I re soldered the connections to the 2 chips after looking over the schematic more closely (using fresh solder as recommended) and the problem as gone away! The problem was a bad connection to the TDAxxxx chip that served the right hand speaker. The chip appears to be under tension when everything is bolted down tightly, it lives at the edge of the board where it is soldered to the board but is mounted to a heat sink that is bolted to the chassis. I can see where the chip could take some shearing action if the amp was dropped.

Thanks for your attention all!

Good job, congrats!
