I have a hunch that a cap that switches over from RX to TX - and back again - it causing it to discharge and act as the "power supply" but there's nothing to sustain it - so it falls to zero. At least it should - acts like timing function to help the Mod amp do it's job...but it may not work because when you pulled the limiter - which this thing powers - you still had the cutoff. So you said you recapped it - please double check the work...

Works off of 8V constant, C113 - down by the ALC/AMC control pots - if it's shorted, the 8V constant pulls the TR/Q 28 right back up to ON - so if you haven't replaced it - try putting in a new one and see if this works.
