Saratov, 04/1970 - This 'RF Oscillator Tube, a ECC42 clone' according to Franz Hamberger, looks very much like 6N3P - tiny plates, smallest ever built in noval package. But the rest of the tube is different - see photograph for comparison. Unlike the ringing 6N3P, this one is shy and needs no special anti-oscillating efforts.
