Hi!I suggest you try to test one amp at the time.
First, short circuit the input of the phono amp. Still hum?
No, you have a problem with your turntable and the cables. Does the ground cable work between the TT and the amp? If you have changed the pick, do you have loose cables at the pickup? The four cables are mixed up?
Yes, test the phono amp alone only with a headphone connected (with 100 ohms in series in order to protect the phones).Still hum?
Yes: Some problem in the phono amp.
No: Some grounding problem, between the phono amp's power supply and the tube amp.Did this make any sense? Have you tried to twist one plug in the outlet? Can reduce hum.
