Caps were changed according to schematic. I have notice this before in previous projects that components are different from schematic and under chassis. What was the reasoning for this ?
Is this a bad thing to replace components per schematic as per what is in radio.
There could be many reasons for parts not matching the schematic---eg they might have run out of a particular value, or someone figured out an "improvement" and did not update the schematic.
If the schematic and the actual set don't match, then you can go by other similar circuits or good old-fashioned trial and error.
NOTE: We can't see the schematic you linked without being member(s) of radiomuseum--I checked nostalgiaair and it's not there.
