- Notes
- > Codes Valve 1: +Δ k6B; Valve 2: Δ+ k6B. These both have k6b design code - extremely rare, and very early - they pre-date the original British Mullard k6 type, the square-getter k61, by more than twelve months. Valve 1 made at Mullard's continental supply factory, Philips Copenhagen factory, Valve 2 probably made at the same factory, although the factory code triangle is a different shape to the recognised shape for Philips Copenhagen, there is no factory recorded using the actual triangle shape on Valve 2's base) Code details were a looser concept in those days. - ebay seller, > Codes Valve 1: +Δ k6B; Valve 2: Δ+ k6B.
