Under the lamp is more than an octane in the radius of the contacts.
The extension cable is designed for measuring parameters and characteristics
of electrical signals directly on the electrodes of vacuum tubes in the “hot” mode. The device is inserted into the lamp panel instead
of the lamp, and the lamp is included in the extension cord.
Contacts from each electrode of the lamp are placed on the body of the device, which allows measurements
to be made directly during the operation of the radio lamp.
