I'm attempting to repair the old Zenith 9-S-55, and I'm confused. the schematic I have is from an old Rider publication, and it lists the resistors used in the unit, but the are described as 99M ohms, 49M ohms, 990M ohms, etc. I am unfamiliar with these units. Would the 99M ohm resistor possibly be a 99K ohm value, indicating the M value was previously used to represent thousands?

Henry,
You are right. Some older schematics used m instead of k. They would then use meg after the resistors we normally see marked m on more modern schematics.
