Alignment of old Philco Radio
#3

Be aware that signal generators are very often not accurate so it may not be wise to do adjustments without verifying the dial. For your 620 you will need 460KHz with AM . Aligning the IF properly is VERY important so I suggest that you don't try it without borrowing someone's frequency counter first. (shut the AM off when using the counter). A last note on your 620 IF- once you align it, NEVER go back and tweak it for better reception anywhere on the dial.

The 620 is an excellent radio! Depending on where you are located and what you use for an antenna, you should be able to pick up stations from several continents with ease.

DON'T CLEAN THE DIAL WITH ANY LIQUID!!!! Just use a dry brush to get rid of dust. New dials are readily available but the originals are still nicer.
