My TC-50 has a noticeable hum. Sounds like the transformer humming.It is noticeable When I flip the switch up on channel 2 an 3. If the gain is past 12 oclock it is pretty loud. If I dime the gain on channel 3 the hum is ridiculously loud. I tried changing all tubes and bypassed loop,reverb and boost. Also tried different cables.no cables and the result is always the same.Is this normal. Does your TC-50 have a hum?
