Hi Amie.
Cannot say I've had trouble in that way. I did have some issue when I made an RIAA equaliser and preamp for my Pye Black Box to enable the use of a low output ceramic cartridge. The issue was hum, I tried everything till I screened the valve with some thin steel tube of the correct diameter which effected a cure, it was caused by stray magnetic fields from the gram motor.
