AN/JM Wonderland grounding

[galtjunk]

I see that the first 3 PS caps ground at the power transformer tab.
The next one is marked Send/Receive. Is that to be grounded at the Send/Return Jacks for the effects loop?
The next two get grounded at the tab by the input jack.

Where does the Reverb transformer get grounded?

At the RCA reverb output connector going to the tank. (What i would do)
