Thanks guys, the switching of the plate leads fixed the squeal in pentode mode and the grounding of the secondary's common wire fixed the prescence + resonence controls. However, now, when I switch the amp into triode mode, it shrieks, any suggestions? BTW, in case it matters, there's 550v on the plates, with the tubes sucking up 70ma of current (2x6L6).  
Thanks again! ...Spencer
