I'm still chasing down the hum. I did the star ground off the volume pot's ground node, so this might be the problem. I'm going to move the ground point over to the inputs and use heavier gauge bus wire. I was using wire that was thinner than the in B+, except in the connection going to B-.

Hopefully all will be sorted out this evening. Now if I can just figure out how to tune in something other than WLW......Colin
