When you hear crackling - then I worry.

The issue of IC4 (4558) begins to mount.

Check the parts - these Galaxy radios were often prone to cracked (as in open) resistors - the crackling sounds are more than likely from the Receiver side - so there may be open lines or failed caps in the RX section.

More than likely - power feeder filter caps.
