Here are 2 Amperex/Hewlett Packard branded made in GreatBritain
by Mullard
12AU7A/ECC82
twin triodes. These tubes have been tested on a TT-1 H
eathkit mutual conductance tester.
A reading of
1420
or more is indication of a good tube. I
guarantee these tubes are useable. They test: Gf2 B1J4
1750/1850
and Gf2 B6E5 17
00/1850.
I will attach readings on the tubes and can combine shipments.
Please wait for an invoice on combined shipments.
