XS series issues
Posted 21 July 2013 - 05:31 PM
I replaced the faulty parts and all 8 output transistors, TR220, 221, 222, 223, 216, 217, 218, 219 ( i found found this to be best practice for reliability to change them all)
So apparently i missed something major cause upon power up TR215 exploded and the following components had a meltdown: TR213, 211, 210, 214. D209, 215, 214. R229, 227, 260, and 224.
Diodes 215, and 214 seemed ok before applied power.
Any ideas what i did wrong here?
Also i have an xs900 that had a shorted IRF540N in it and i can't seem to find the problem with it either.

There is always a good reason to purchase parts through a responsible and reputable outlet (Crown authorized dealer). Most Crown replacement parts are reliable and have been tested and graded (ie. for power transistors) so that parts and circuits mesh well with each other. I agree that in most situations, a part from a jobber will do the trick. But falsified/counterfeit transistors? (Who does that??) I HIGHLY recommend to choose genuine Crown replacement parts for those tight and precise operating circuits.
