Hi Keefer,

The noise from touching the radio may go away when actually installed in a car. The radio case, frame and the user will all be at "equipotential' in the "Faraday Shield" that is the car body.

As for alignment, for an AM radio, if careful and mark where all adjustments were and be slow and gentle, one may be able to "peak" the IF stage by ear. There is a trimmer, usually on the frame of the radio to match the antenna to the radio. If the Radio is capacitor tubed, there will be trimmers on the tuning condenser. the trimmers for the RF can be peaked on a weak station midpoint and checked against the lower and upper limit of the band. the trimmer for the oscillator sets the beat frequency. touch thqat last and only if everything else has failed. Again, matchmark before adjusting, turn only a small amount at a time and if no effect, or adverse effect, return to original position. If the radio is inductively tuned instead of capacitively tuned, don't mess with it.

Good luck
