ECC83, Telefunken , Smooth Long Anode, Two Hole, Berlin Sept 1960 Production
On offer today we have a TELEFUNKEN white print ECC83 made in Germany . The base carries the characteristic diamond instamp, the print is very slightly smudged.
For Va = 250 V Vg = -2.0V against a nominal specification of anode current Ia = 1.2 mA and mutual conductance gm = 1.6 mA/V, the following results were obtained:-
A1 Ia = 1.0 mA gm = 1.3 mA/V
A2 Ia = 1.1 mA gm = 1.5 mA/V
As you can appreciate this represents good matching of each triode section within the envelope and an EXCELLENT device.
