For the few cents apiece, replace the resistors, all of them. Capacitors as well. Make sure tubes are in their right place, correct and patent. VTVM or modern digital voltmeter will always read high on signal voltages. Reason is that load imposed by the meter is almost negligable, but old time meters did serve as voltage dividers, and back then that's all they had.
