Tom,
I guess we posted at the same time.
The wires inside didn't look too bad and some have certainly been replaced. The leads with the plugs though are showing age bad. I'd like to at least replace those and the grommets at least. I've already considered just living without the fancy couplers.
Runs well enough otherwise. The e unit is sluggish but I've noticed that with my 763 also. I guess when they mostly sit on a shelf they don't get enough exercise 🤣
