The YL1080 is a quick heating version of the QQV03-10 VHF transmitting double tetrode. This exhibit was made by Philips in Holland.
This valve is designed to operate in the VHF frequency range 67-200 MHz. Designed for oscillator, multiplier or PA service it was planned that this valve would operate in class C. The anode dissipation is 4 Watts per anode and an RF output power of up to 12 Watts was possible.
The anodes are on the left and right of the central column. The beam plates, screen grid and cathode are common to both sections.
Face view of one anode with the beam plates seen as notches either side.
Thanks to John Sykes for sending the photographs.
The thin glass tube envelope is 20 mm in diameter and, excluding the B9A base pins, is 68 mm tall.
Reference: Data-sheet. Type YL1080 was first introduced in 1960. See also 1960 adverts.
