Assuming your R-27 is stock, make sure it has a
plug-in installed in the front.

The +24V line runs from the rear panel, up to the
connector box in the front of the receiver. Then
from another pin on that box to the filaments and
dynamotor.

For the typical remote control installation, the plug-in
had a jumper to make the 24V power connection, in
a local control installation, the plug-in held the sensitivity
pot and CW-OFF-MCW switch.

The screen voltage connection was used in a test bench
setup, it is not used in operation.
