greh OP131 posts When I first power it up, the hum isn’t audible until I’m about 30 minutes into listening. That could be caused by a filter cap in the power supply going bad. Does the hum sound like this? 120Hz hum. https://www.youtube.com/watch?v=pC4Uzt0qm2E Or does the hum sound like this? 60Hz hum? https://www.youtube.com/watch?v=SVZ2P0KsLic . |
