Hello , can anyone supply me with a schematic diagram for the internal components inside the phillips 300ssb cb .
Now that's a rare one. What little info I could find indicates it has a uniden board inside. If you can find the board number someone here may know of another radio that uses the same board that there is info available for.
Look for something like PC-xxx, where the x's would be numbers. There may also be some letters trailing, so then it would look something like PC-385AG, for example. (Stalker IX uses that board for at least one version.)
