This SB made some squeaks and pops when I got it. Let's start with the speaker and MPU are good. All of the test point voltages test good 5v, 12v, and 43v, 67v on + of C17. I socketed/ replaced the amp at U9 and get 2v at pin 2. I replaced U1, U4, and U11 with their respective replacements. Reflowed all the pins at J1 and J2. replaced the caps at C17, C8, C11 & C6. Replaced the diode at CR3. Replaced both pots. The only problem I can find is the voltage between the shared points of R3 & R5 is 0.9vdc and should be 2.5vdc. I have added another ground point to assure it's getting properly grounded. I do not know why and cannot figure this out. If there is something I have overlooked, please point it out to me so I can get on with it. I'm tired of looking at this SB and need some sound on my paragon. It now makes NO sound at all.
