Joe,
Make sure you're measuring against B-, the negative end of the filter
cap, and not to the chassis, which is DC-isolated by C8.
Listen for the local oscillator on another radio, to make sure it's on
the appropriate frequency. If you tune to a station around 1500 on the
second radio, you should hear a beat when the set under test is tuned to
1045, (1500 - 455)
Good luck,
Al
