Ex-Soviet era GT308V germanium transistors.
Sometimes known as 1T308V (don't confuse the english and cyrillic alpha characters B and V!)
p-n-p, Hfe 80-150 spec
NOS germanium transistor
Generally low leakage and great tone
Used in a number of classic fuzz projects: FuzzFace, Rangemaster, Tonebender, FuzzFactory etc.
We sampled a number of these, values range from the low 40's to the high 70's
(note: hFE of a transistor is the current gain or amplification factor for that transistor)
