I have in my parts collection what look like a complementary pair of power transistors, of Tandy origin, from years ago, part numbers RS2019 and RS2027.
I can find reference to the 2027 being an MJE34 but I can't identify the RS2019. Same package and if they are complementary the hFE's measure around 70. The packages appear to be TO127's. Does anyone have a look-up list that will identify the 2019 (presumably Tandy part number
276-2019) and the 2027 (276-2027)?I want to use them in place of a TIP29 and TIP30 in a power supply circuit (ca. 1975 vintage) and I'd like to check that the two I have will do the job.
TIA
