Ok Jtinn, some progress. I lifted the ground on the vk60 with a cheater plug. No change. Used a extension cord and plugged into a different circuit, with/with out cheater plug. No change. On a whim, I pulled the interconnects from preamp to amp. Hum doubled or tripled. Seems like it is in my amp now. Bad tubes? Old tubes? Something else in the amp? I've had the amp for just over a year now.
Thanks
