Anyone using the TB with Tube amp? I got no problem with SS amp except Tube amp. Other devices don’t have problem with TB either until I hook up the TB. Very loud hum
Does your Tube amplifier have a coupling capacitor in the input?
As shown in this wiring schematic, add a coupling capacitor to the amplifer circuit at the point indicated by the red arrow.
Thank you, I will have to order the cap and try later
