Champ: squealin' & tickin'

Champ: squealin' & tickin'
Built a Champ (5F1) that sounds great, except when the volume is about maxed. The amp occasionally squeals then and sometimes I get this funny ticking sound (a time bomb??). I've isolated this to the output stage. My input jack is isolated from the chasis and all low-signal wires are sheilded. Am I just feeding the 6V6 too much signal? Thanks...

Are you using any NFB in the amp? try reversing the leads on the OT primary and see what happens
