hi all, hoping you can help
have two aging beta 1s, they get fairly light use in the school where I work,
2 consecutive channels are constantly on, I bought some triacs and fitted to the relevant channels
but did not solve the problem
the triacs I removed are T2513MK, and the ones I fitted in their place are BTA25600B
so my questions are
have I fitted the right triacs? and could I have wired them incorrectly?
could there be another fault?
any help with this will be greatly appreciated
steve
