for now anyway ;)
I had a replacement EZ80 (rectifier?), did some reading on the dynaco forum here, and learned that if that tube is going bad, it could cause hum.
Replaced it with a used telefunken from the bay, and much better now. Still a bit of hum but you have to really listen for it.
Next I will try resoldering existing ground connections and adding a few new
ground connections to all the boards.
Forum recommends and that will be much easier than replacing that quad cap. From what I read, the board tracings are extremely fragile. I could easily do more harm than good if I am not careful, and also lucky...
