• I'd just do it by eye. You might see something is obviously loose or feels loose.

    Also, if it wasnt doing it before repair, and is now. Then it's something to do with the repair (simplest answer) so check that. The amp is grounded inside, so take the case off (with power unplugged) and check in there too.

    If non of those fix it, then needs more investigation.

  • Thanks, I'll take a looksee.

    CD player plug was not 100% engaged, we'll see if that changes anything.

  • Further to this issue, I don't think it's actually the stereo itself, unless it's extra sensitive because the pops always happen in relation to other things happening in the house, like when then the furnace or drain pump or fridge start/stop. So basically I think our house is wired badly, or improperly grounded. To be clear, it didn't start after the repair, it just seemed to happen with more regularity and volume. We also switched receivers, with the HK now upstairs and the NAD down in the vault.
