OC44 Germanium Transistor, used by the Rangemaster
[OC44]

OC44K  Tung, Germanium Transistor

With metal envelope as used in the most of the original vintage RangeMaster by Dallas Arbiter.

NOTE:
The older version with glas envelope, which had been used in the earliest RangeMaster ever made, we do not stock. The far majority of them are extremely microphonic, have even higher hissing noise and finally are more expensvie.
