What is the function of this triac in your power supply? I have come across a triac which is used to switch between 115V and 230V input in the PSU of a DEC 3000/300. My triac went short circuit which caused some release of magic smoke when the PSU was used on 230V. I also had difficulty finding a replacement for it so I ended up leaving it out. The PSU worked fine on 230V only without it once I replaced the other damaged components. If your triac has a different function, ignore the above. Regards, Peter Coghlan.
