Hello. I have an xs500 amp that had a couple shorted transistors in it, T215, TR221
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.
