The measurements are made with a 3&0 vacuum-tube volt-
meter RV 7 in the field ohm X 1, and with the receiver
switched off.

The ohmic values are stated with "Ca" as they may differ a
little, depending on which measuring instrument used.

Below ohmic values can be measured when the transistors are
mounted in the receiver and when these are OK.
