CV4069=12AU7 Brimar UK NOS with flying leads (no pins)
21) CV4069=12AU7 Brimar UK "Black Plates" 1969 NOS (flying leads instead of pins)
CV4069 Brimar=12AU7 with "flying leads":
Type CV4069 made by STC/Brimar of England. Internally, they are identical to the Brimar CV4003=12AU7/ECC82, normal size and shape, but they don't have any pins! Instead, they have nine wire leads. I have read an old spec sheet on these and the story is that they thought these valves were so reliable that they would NEVER need replacing.
