DC30 2ND channel issue

[playonit]

Just finished a Ceriatone DC30 my second build... while fun it's giving me fits ...part of the fun right???

Got amp started up and channel 1 is sounding good but channel 2 is having issues..... The channel only gets sound if volume knob is turned to zero.. any other movement I get scratchy and pronounced hum and no sound from guitar.... Checked wiring against layout and it looks right ...... bad pot??? Kind of at a loss here..

part 2

With my channel 2 problem I am chasing down it appears that not much glow comes from the ef86 all others appear to have more going on in the tube. Is this an ef86 trait or does it sound like a bad tube?? it glows it's just faint.Is there anyway to test the tube without a tube tester since I don't own one?? I get sound but only when channel 2's volume is all the way at zero.... would I get any sound if the tube was bad?? the tube shouldn't be creating the volume only works at zero issue right??? When using the shielded wire nik supplies with the kit does the braided shield need to be pig tailed to ground (confusing on layout) or just solder the core wire to the tabs stated on the layout... all wires match the layout and all have continuity.... I'm CONFUSED
thanks

On the input I would solder the shield of the two cables to the ground of the jack.
At the tube end, trim the shield back 1/2" and heat shrink it.
Then solder the center conductor to A1 & A2.

Same way for C1 & C2.

Thanks Tom.... rewired the c1 - cw2 and a1 - a2 and have full range... now I need to chase down some hum and figure why I don't have full volume??
