I'd take a hard look at the cable(s) which feed 
the oscillator signal(s) between the 2 units. 
When I had a 301/401, I once used RG-58 cables 
instead of the correct RG-62 ones. This caused 
the 401 to do strange things - like next to NO output.

Make sure you're using the correct cables and 
that the connectors are properly soldered.
