Hi Guys,
First post here for me, usually I am able to find the answer buried somewhere but this time I’m stumped. Any tips or advice would be much appreciated!
I’ve got a Roadking I and seem to have a problem with the progressive linkage, as far as I can tell. It’s not the usual “pop” or “click” noise you get when you first switch channels after kicking it on. When I switch into the 3rd channel I get a severe volume drop; it occurs with all possible tube combinations, and ONLY on the third channel. Then, when I switch out of the third channel there is a very noticeable delay from the time I hit the switch to the time the channel actually changes (on my pedal or manually with the knob on the back). This delay ONLY occurs when I change OUT of channel 3. For example changing from 1 to 2 or 4 to 1 does not have a delay in the transition.
I think I’ve ruled out tubes as the issue here as all tube combinations work with channels 1, 2, and 4; be it 4 6l6s, 2 el34s, 2 6l6s and 2 el34s, etc. Everything’s glowing nicely under the hood, and I cannot see signs of degradation to any of the pots, caps, resistors, wires, etc, but maybe I’m not looking for the right thing. I’m no expert but I like to think I'm fairly competent.
The issue occurred suddenly during a jam. I shut it down nicely and then did some testing later. No blown fuse.
Thanks!
