Hi Pulling off the weird mods is always a good idea. 
Once you get that done, think more and do less. 
Wholesale "replace all of this" and "re-do ever one of those" 
that is rarely a good idea on day one (if ever). 
Work your way from the speaker towards the antenna. 
Verify that each part of the radio is working, 
but don’t go crazy getting any one part “perfect” 
until the whole thing works to some degree. 
The bits and pieces interact with each other…. 
One example is running tubes through a tube tester. 
It will give you good data to think about, 
but unless you find one that is just plain dead, 
it’s only food for thought. 
Note which one is which and how good/ bad 
they seem to be on the tester. 
If the tester *and* the circuit performance say the tube has issues, 
swap it out (swap out does not equal throw out ..). 
More thought, more analysis, more research in the manuals, 
less changing things around …
