Re: peavey xr1212
If these two fets are blown, I suspect the driver ic is also blown, check the resistors connected to the gate and follow them back to the drive circuit. I suspect there are more issues, hopefully Peavey will provide the schematics

Re: peavey xr1212
Interesting ... that mixer uses the same amplifier board as the Peavey IPR1600 power amp ...
 The original 2x components were IGBT's but several other fets can be used to replace. Be a good idea to remove the amplifier side power fets and check them or you may blow the new PSU fets again on 1st power up. Last edited by check12; 06-18-2022 at 05:29 AM.. |

Re: peavey xr1212
Peavey is a great company when it comes to providing schematics, etc. They will also sell parts if they have them, and they have had some parts to some very old amps I have repaired.
