So i decided to go through all the component values for the ST20.

Now for some reason the components have changed values over the years?

For example on different wiring diagrams and lists of parts:

R5 can be 47k or 100k
R12 470k or 1M
R13 470k or 1M

C5 0.1uF or 0.02uF

My ST20 came with the original paperwork which has a wiring diagram, i took the values off of that.

So my question is which is right? I think perhaps just follow the wiring diagram my ST20 came with.
