Manufacturer specification sheets

Each tube is supplied with its individual data sheet. Please contact Deep Dark if you require a particular minimum specification.

Tube format and gain control

This is an 18 mm 10160-style tube with three contact pads. The centre contact provides external gain control through a 180 kΩ EGAC circuit when used in a compatible three-contact device.

It can also be installed in a compatible standard two-contact device. In that configuration, the centre contact remains unconnected and the tube operates without user-adjustable manual gain, using its automatic brightness-control functions.

Please contact Deep Dark with your device manufacturer and model if you are unsure about compatibility.
