Have a burnt transistor can only make out these numbers ST 99235 mje 55t the two numbers in front of 55t are missing it could be 2955t or 3055t [ 2955t is a PNP and the 3055 is a NPN] so how can i tell which type this amplifier would take without any type of blue prints.This is a old unit made in the late 70s .pentetrator 200.Thanks .P.S transistor is shorted out cant take any reading of of it.
