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.

TIA,
Bill
Bill,

What case is it in, a TO-220 (plastic case with a metal tab) which
means your radio is likely to be a 21-II, or a TO-1, a small metal
cylinder?(as used in the original, white grill clothed radios) In this
case I'm assuming the output transistors, not the drivers. If I'm wrong
about that and you do mean a driver transistor, please let us know the
case style and (if known) polarity.
