The first thing I noticed when inspecting the innards was too much wire. I suspected this would contribute to the 60 cycle hum so I rewired it.
I kept the original config, just shortened the wires. Thought the members here would like to see pix.
Here it is, as new, looks clean but notice tie-wraps holding bundles of wire.
After clipping the tie-wraps look at all the excess wire!
Here's it is after the wires were shortened.
