What, no schematic? They appear as transistors, but even so, now that you have destroyed them what were they, we may never know. You didn't know what they were, you didn't have a clue how to try to test them in circuit to possibly identify them as NPN/PNP/SCR/Dual Diodes now you are totally screwed. I am sensing a pattern here all the way back to the Tek power supply. I recommend a bigger hammer and oxy-acetylene torch for the newest additions in your repair efforts.
