If possible, I would unplug one of the power strips (obviously the one not being used to power the phono pre). But first, you may want to connect any component being used for vinyl listening to just one power strip. Does your phono pre use a wall-wart power supply or a regular power cord (is that power cord a 2 or 3 prong)?
Turntable Hum
Any help appreciated!
Low pitched hum coming from TT input ...even when TT is not running . Hum is noticeable at about 1/4 volume & really bad at 50%
Manley Monoblock Snappers
VPI Scout w Hana MC cart right next to amp on table (moved TT away from amp to floor made 0 difference)
Allnic 1202 Phonostage grounded to VPI TT (on floor below JBL speakers & main speakers right to the left Tekton Encores)
Manley Jumbo Shrimp Preamp
Klark Teknik 32 band EQ
All cables (interconnects) recently replaced - Mogami
I tried ground lifting the TT motor - no change
unplugged tv & nearby laptop - no change
unplugged all lights nearby - no change
I suppose my next troubleshooting venture is to run a ground from phonostage to everywhere & start touching things? Phonostage seems to be the culprit....
😕
Thanks everyone!
