Tried posting this on the main w492 thread.  Was wondering if anyone had some test points for voltage on this circuit.  3 of the 4 bands are working fine.  Both of the units the third band (upper mid) arent working and I'm getting almost full + voltage on the switch for that band which i dont think is right (since none of the other bands have that).  I've checked over the schematic and cant see where that could even be coming from.  Ive also tried different IC's, no different.  After reading through the build thread, I haven't seen anyone with this issue.  PS they WERE working fine at one point, nothing looks like it got fried and without removing all the components, its hard to tell.
