SB-201 Amplifier idle current

[Bill Collins]

I have a Heathkit SB-201 Amplifier.  In the manual it says on Page 46, Operating procedure, "Place the meter switch of the linear amplifier in the Plate position and push the OFF-ON switch to ON.  With no driver output from the exciter, the linear amplifier meter should show idling plate current of approximately 90mA.  I don't get the indication at all on the meter.  The guy I bought it from said it's always been like that, but everything else seems to work fine, except the Rel Pwr Sens control seems flakey.  I haven't had time to check it, and really don't know where to start. (Read somewhere just south of an appliance operator-HIHI).  Anybody have an idea where a RANK amateur could  start?
