Key Features
- Low internal voltage drop
- Operates without generating r-f noise common to mercury vapor tubes
Application Notes
The cathode should always be allowed to reach operating temperature before the plate voltage is applied. For average conditions this delay should be at least 30 seconds. Plate leads from the power transformer should be of flexible wire to prevent strain on the top caps. Connection to the top caps should be made with a clip or spring clamp. The lead wires must not be soldered to the top caps.
