EF86 Rohr RFT, QUAD ABGESTIMMT VON ROETTEST KURVEN, NOS
97,01 €
Tested with Roetest V10, a wonderful german machine for testing tubes, it shows everything about a tube. Tubes are unused, never inserted in socket except testing procedure described below. One point match for Ip and Gm is a good compromise but is a joke comparing with matching by curves.
