OC45 Valvo

The label was probably added for the German military. About half the lot have gains under 40. Another third run 45-65 and will work as RM devices on their own, and the remainder hit Fuzz Face buckets 70-100. All measurements by the "Bare Bones" method: Normal room temp, 9 Volts C-E, 9 microamps into the base. Leakage guaranteed 200 microamps or less at room temp.
