Hi,
I'm looking for the elusive audio driver transistor in the KLH 21-
series radios. It is house marked as KLH5351. Early 70s.

Any help would be appreciated. The normal sources are turning up dry.



It's not listed in the 1985 ECG index (ECG212M). There are a few KLH
parts listed but not that one.


FWIW, 1996 ECG has a KLH5353 = ECG197:
PNP -Si, AF Pwr Output
Vcbo = 90 V
Vceo = 80 V
Vebo = 5 V
Ic = 7 A
Pd = 50 W
f sub t = 0.8 MHz min
h sub FE = 20 min
case: TO-220
