Here is another questions for those out in radio land.
It seems to me that in many cases, the radio I am working on, and the schematic don't agree.
(A) For example the schematic may say that a capacitor attaches to pin 2 but on the radio it is pin 3.
(B) The schematic says that the electrolytic caps should be 20 25 30, but the cap in the radio is 10 20 30.
I know in some case for (A) one of the leads may attach to B- so it may be that there are many options for this, and in (B) case, the radio has been repaired so they may have substituted.
My question is, when I encounter a difference between the radio and the schematic which should I use. I don't have enough or ANY real electronic experience to make an educated guess about differences in pin numbers. My gut tells me, to put it back together the way the radio is presently wired.
Any thoughts ?
