I've been searching high and low for a proper step by step,instructional kinda video/manual, for biasing the tube power section for the Line 6 DT50, but to no avail.
I think it's high time, the forum have something like this in place so we can do the maintenance ourselves. Last i check, it cost nearly the price of a single tube to send it to the amp tech for biasing...
Hope any guru out there can help? =)
