The Rtrans-prim is the Resistance of the Transformer's Primary, and it can be measured directly across it with an ohmmeter while still in the circuit, because it is about 2 orders of magnitude lower than the rest of the resistors that are in this arrangement can be considered in series with it.
I theorised it would be on the order of 1-1.5kOhm. Even if it is Zero it would not change much for the same reason - it is small compared to the rest of the resistors.
