My 5f2-A has a high pitch squeal on start up (Much the way you would get when you have to swap the plate wires on a amp w/t NFB) Since there is only one plate wire,I'm very confused? I've double checked my wiring, All looks good.My guess is it's a grounding problem? or a defective OT? Thanks in advance for any help.
