Hello!
Wondering if someone could chime in on whether shielding a power transformer is likely to reduce hum on nearby equipment?
I have a pair of EQs racked in a 1U case with a toroidal transformer in as well. There is a slight amount of hum from the transformer and I'm interested to know if this can be reduced by covering with a metal case? I can't feasibly mount it any further away from the EQ cards in the case.
I also have a Juno 6 which produces hum on the Rhodes that it sits on top of. I've tried some basic foil shielding under the power transformer with little effect. It looks as though the 100V transformers Roland used in their domestic Junos had full metal covers, where as the export 240v models have a plastic bobbin with only partial metal surround!
Same question for the Juno - could a replacement transformer, or suitable transformer cover reduce/remove the hum picked up on the Rhodes?
Thanks!
