Application Notes
Designed primarily for 'storage' purposes in telephone circuits but has applications in electronic counting. Valves are light sensitive and should not be exposed to direct sunlight, but require a small measure of light for satisfactory dynamic operation. If enclosed, a small light source should be provided.
