Listing Detail Tabs


Two genuine Dutch ECC82 12AU7 from the famous old Heerlen Holland factory. These were both made in late 1962.
Their design version is the Gf7, as marked on the glass.

* From the same batch, early October 1962 ('2J1' on glass)
* Early Miniwatt box with the pin diagram
* Gf7 Heerlen Holland type, printed on glass
* Two seams in top glass
* Both valves an excellent match

Seriously tested on a DC-regulated modded AVO163.
*These two valves are essentially identical to each other.
Each valve has the two triodes testing at around 11.4ma and 10.3ma
(book spec is 10.5ma @ 250V anode, -8.5V )

NOS easily can range from 8.5----13ma, so these two valves are an extremely close match...

So a great chance here to get a super matching pair of 55yo NOS old Heerlen ECC82.
