[TenTec] Paragon PLL Major & Minor Board

[Gary J FollettDukes HiFi]

What is wrong with yours?

No lock anywhere or just upper or lower bands? 

The most frequent (by a LOT) failure point on this PLL board was the solder connections to parts on the board.

The reason for that is that Ten Tec trimmed the component wires too short prior to board stuffing so a lot of leads did not get much solder on them. Parts would often work their ways loose.

If you know which function is not working (one PLL or the other) I can probably steer you in the direction of where to resolver all of the connections.

You might also try LOOKING at the foil side of the PC board, checking to see if any of the solder points where parts are mounted appear “short”. Those would be low hanging fruit..Desolder those types of connections thoroughly, reseat the respective part and resolver with at least 1 mm of wire poking through the foil on the board (and that is a MINIMUM!).
