Pair of Amperex ECC186 7316 for HP 1959 D-getter Holland Vacuum Tubes

Pair of rare Amperex ECC186/7316 tubes, labeled for and selected/aged by HP for use in their test equipment. These feature large D-getters and 1959 Heerlen, Holland, codes. This is my LAST pair of these at this time! Test results (measured , typical NOS). 2150/2150 & 2100/1900, typical NOS is 2200/2200. I have over 30 years of experience in many facets of electronics design and repair. Tubes are described, tested, and presented to the best of my ability, subject to the limitations of the equipment that I have available (Hickok 539C and 6000A). Test results are likely to vary some between your equipment and mine due to the imprecise nature of 60-year-old consumer-grade test equipment. Tubes are not tested for noise or microphonics.

They are often wrong by a considerable amount. Neither buyers nor sellers are allowed to request holds or redirects. This protects both you and me.
