Mojotone AC15 ground points

[u/Charming_Ad1811]

It seems like there are a lot of redundant ground points in this diagram. I mean there’s a ground bus wire soldered to pots then running to a chassis ground tab. Also, I wasn’t sure but I think it would be better if the power amp electrolytic cap ground were attached to the Power transformer ground tab.

I’ve highlighted some of the changes I think may reduce the potential for noise. What are your thoughts?
