[Boatanchors] TS-830S

I'm repairing a TS-830S, and the last thing on the list is no Drive
indication on the meter in the ALC position of the meter switch.  I've
measured plenty of drive signal on a 'scope, but nothing on the meter.  I
know the meter works because I can see the HV.  The 6146's are removed
until I fix the drive meter problem.

I'm assuming there's a circuit somewhere that samples the Drive signal and
rectifies it for the meter to read, but I can't find the circuit on the
schematic.  Can someone tell me where to look for that circuit?  I'm
guessing (and hoping) there's a blown diode that needs to be replaced - if
only I could find it.

Thanks - ed, k9ew
