[Jukebox-list] FW: Seeburg STD4 double scan & no selection

[Dieterle, Jeff R.]

After going through the circuit in the manual and following Ron's
description in the Sequence of Operations I'm wondering if cap 3104 in
the pulse detector circuit could be the culprit.  If its not charging
rapidly & leaky wouldn't it impose a high resistance and keep the SCS
from allowing the trip coil to connect ground ?   Pardon my ignorance if
I got this circuit operation all mucked up.
