Thanks. There was some black shit in the board near L43 covering the board label so I couldn’t see it and the Sam’s facts pics didn’t show it.  But either way it look fine, doesn’t look popped that I can tell.  I actually had pulled d49 and 50 out of my parts radio before so I don’t think they are the problem.

But to answer your question about what I’m up against? I have no fuckin idea and I’m almost done with it. Because it probably isn’t anything huge. I just can’t see it. 2 months and more working on this radio in virtually every part of it.  And now all this.

But anyways pretty good bet the driver is toast. Check out this pic of it.  Hard to see but the plastic casing is completely separating from the metal back. Problem is why did that happen and I’m afraid the replace my may burn up too.


I was able to find an NTE equivalent for D50 if I need it. But having a hard time finding one for D49 (MV 13 HY). NTE cross reference brings up 2 when I put in just MV-13 but not sure if either is ok? NTE 116 and 177. Either one a match? Not sure I need it but just in case.
