VHF push-pull transmitter, like the rest of the QQ series. Double tetrode with a common cathode and common g2. Interesting pinout isn't it?
I have some QQV03-10 valves that I intend to try for audio. They are supposed to be quite good.

Both types incorporate built-in neutralizing capacitors for VHF/UHF push-pull operation. Easy to tame up to 450MHz. Wasted on audio.
