Lee -
R192 is not in series with the relay coil.... It is a "fuse" resistor
in the +250V bus, and first appeared in the Version 9 TR-4C.
The 2.5k relay didn't show up until Version 12, at s/n 42500, and the
series resistor is R194. It's does not have the 1W designation on the
schematic, but the ones I have seen that were factory installed were
indeed 1W resistors.

The relay in my TR-4C is indeed has a 2.5K coil but the resistor in
series with the coil is 27 ohms @1/2 watt. It is R192.
