Went and picked up some new JJ’s and it still won’t power up or show any lights… Any thoughts?
A faulty power supply? Can you test it?
+1 on the power supply. Tubes won’t have anything to do w/ the LEDs.
thanks for the replies guys…no way of testing the power supply unless I take it to guitar center on the weekend.
