For those of you that have the STE exciter, I've obtained some 2n2804 and 2n1308 transistors. Those and the 2n2219 (2n2222) appear to be the big failures in my units. one thing i haven't located though is the 2N350A pass transistors for the + and - 12V and 37V for the finals which btw are a 2n3553. Is there a reasonably priced sub for the 2n3553 around? Larry W0OGH
