Oh and don’t deviate to much from the original design in any kind of repair work . ( including components specs )
Things are the way they are for a reason , I would not trust myself to do that.
This is a case where a little knowledge becomes dangerous .
You may think you have better idea than original designer but you don’t
they may very well have accounted for parasitic properties of the components when designing the circuit or other peculiarities a component can have.
So just throwing in “better” stuff might not yield the results you expect .
There are to many tweaks around the net either doing nothing or making things worse
