Hi, I’m using a 951 at the moment to create quite a few recordings and while the unit is doing its job well there is a noticable hum from the deck. It sounds like a tramsformer hum but is only present when the transport is recording or playing back. I have swapped the motor from another 951 but it still remains. Could there be an issue with the grommets the motor is mouted on (although they haven’t hardened over time) or is there some part of the casing which could be dampened down somehow? Just be nice to have it as quiet as my other decks.
Stay safe guys.
