I have a K Line engine (K3330 3420 with K Line Real Sounds) and the sound card needs replacement. are there recommendation for 3rd party cards? From the engine their is a flat 4 pin female connector to the Tender. The control card has 4 outputs labeled BR (BROWN), BL (BLUE) RD-ROL (RED), BK-WHE (BLACK).
Specific recommendations of cards and techniques to change the sound card are appreciated. Tom
