Yeh, unfortunately that is true.  You will lose screen voltage and 
dynamotor B+ output measurements unless you are able to tap into pins 5 
and 7 on the rear of the receiver.

It's a bit kludgey, but you can connect a pair of wires to pins 5 and 7 
of the rack receiver connector (unused) and lead them out through one of 
the rear phone plug openings to a two pin connector.  Then make a "Y" 
cable that has a PL-152 on each end to plug into the I-84-B and one of 
the PL-152 mating connectors on top of the the racks.  You will have to 
redirect cable wires to the *rack* connector from I-84-B pins 5 and 8 to 
the new connector.  Labeling of each PL-152 will be important for future 
use! :-)

Anyway, that's one way that is reversible to get full functionality from 
the test meter(s) when using a receiver rack.
