I have biased other amps in the past, no issue there. The issue is I was hoping there was an easy "external" way of adjusting bias - a nice easy adjustment like on the old Fenders. Didn't want to have to pull out the amp "head" portion to get to the bias adjustment. Was hoping there was somewhere near the tubes where I can adjust it, and I didn't see anything obvious.

once you open the amp, it's really obvious, and I think they're even labelled bias.

It's a white connector near the power tubes on the PCB, with 3 pins., and the bias pot is close to them. I don't have a photo, but if you are aware of the dangers of tube amps (i.e. they have leethal voltages inside them even wieh turned off and unplugged from the mains), and you have some experience of biasing a tube amp, you'll be able to see the bias points straight away.

Can someone show me where the bias adjustments are on a DT50? A picture would be most helpful. Thanks much!
