120V Initial Testing
- I installed the original 4CX1000A tube which came in my amplifier. Only the 3.2A fuse was installed, and I applied power!
- The meters illuminated; after the time-delay relay closed, the dials also illuminated. The "ON / OFF" switch functioned.
- Opening either the top-lid or the front-panel removed the dial-illumination, and prevented operation of the "ON / OFF" switch.
- I tested the Thermal Overload switch K102 by moving it out of, and back into the airstream - it works, and disables the "ON / OFF" switch when there is no airflow over the sensor.
The Safety and Control seem to work. The Bias and Filament adjustments work.
