I have one record with hum on it. I was troubleshooting the hum until I noticed that playing another record produced no hum. There is hum on the Dynaco 4D demo record.For hum I would check cables and phono, pre, and amp connections, and not want that filtered out. And rumble is not an issue with a good tables and nicer records. Of course 78s are a different story, I can see how they would require some additional work over LPs.
