1 = Gate 1 (amplifier 1), 2 = Gate 2, 3 = Drain (amplifier 1),

4 = Drain (amplifier 2), 5 = Source, 6 = Gate1 (amplifier 2)

T = Telefunken

Y = Year, is variable for digit from 0 to 9 (e.g. 9 = 1999, 0 = 2000)

CW = Calendar Week, is variable for number from 01 to 52

Number of Calendar Week is always indicating place of pin 1
