Hey guys n gals just picked up an SCR8 that needed some restoration. The unit was super clean except it wasn't working. Well I got all the issues restored as it pretty much was normal stuff wrong with it. One of the big issues was because of it being here in Florida it had plenty of moist salty air all it's life so some corrosion caused many of the problems including switches, pots, antenna and tape head. Got everything working great now including tape deck which needed usual cleaning, new belts, pinch roller and head. All the grease needed removal due to it being stiff and the usual issue with heads not going up all the way to play tape properly needed repair.
Anyway I got all of these issues taken care of except for music search. I did notice the Variable Resistor for music search sensitivity was corroded so I replaced it but with no luck getting that working yet. I have tested some of the components with no luck finding culprit. I've gone through scheme but just can't figure out where to go next with it. I've searched here on forum with no luck finding similar issues. I'm hoping someone else might have had this problem and maybe found solution or maybe just trying to get idea of where to go next as it's really got me boggled. Here is one scheme with music search area. The other is here in downloads on forum but is hard to read on phone. Thanks!!
