advice needed: restoring 47-1230 - FM & AM now works!!!! :D (uncertain about SW)
#15

the Phono switch still amplifies the hum from the phono, leading me to believe the power stage (section 1) is correctly wired, and the amplification stage still works.

However, no more AM is being received.

Is it possible a component non-related to the redone wiring has failed?

I double-checked the connections prior to applying power, and tripled checked once I didn't get AM. The soldering seems OK with continuity test, the capacitors polarity is good and all the components are as they were prior to the change (minus the change of e-Caps) I used 450V 22uF for C102A, C102B, C103.

I don't think there's anything wrong with the new caps, what could I have made bad?
