[QUOTE="Disciple, post: 106451, member: 56"] Talk about resurrecting a thread :) So tonight I did some rearranging and plugged my RM1250 back in after it sitting for a month or so after opening it up and checking out it's midi board to compare to a bad one. And my tubes glowed like no other blue and red in the middle like mojo's. The biasing wouldn't do anything. So after a few seconds I shut it down. Let it sit for a bit and reset bias knob for each and tried again and turned each all the way down and still nothing. Thoughts on what's going on? It worked fine before I opened and put the top back on, possibly pushed the biasing pots on accident maybe causing the issue? Need to call Randall in the AM and see they suggest and if they have a few of these pots handy. I peeked inside again before posting this and man those biasing pots have no support so they have to go in just right or risk getting pushed against the spacer ring. [/QUOTE]
