I've reached a point where I need some help on where to go next. SCHEMATIC LINK
My first question, does anyone know which position the band lever switch should be in for broadcast (this is a zenith 8s359) There are 4 positions for the lever, LEFT>LEFT CENTER>RIGHT CENTER>RIGHT.
Tubes (except the indicator 6U5) and pilot lamps light up but I'm getting no sound. I do get a little static when probing some of the voltages. I've recapped all caps and changed out many of the resistors. I've checked the various coils and they all seem to have good continuity. Power transformer is good and my voltages look as follows:

I get a little static from the speaker when my probe is on the 6F5G plate (pin 4 rather than pin 3 noted incorrectly in my chart).
With the indicator tube out of the socket I get the following voltages in the indicator socket.

Appreciate thoughts on something to check next. Thanks!
