I performed the fused bridge mod on my Firepower and I keep blowing the 4 amp fuse for BR2, the coil fuse. I can play for about a minute and then the coils go dead after the fuse blows. The 2.5 on the P/S board is fine. I measure 40 volts DC coming from BR2 which is way higher than the 28 that it should be. Is the bridge shot? Is this causing the fuse to blow?
I also measure 17 volts and 18 volts at the two AC lugs going into the bridge. Schematics say it should be 25.5 AC. Problem with the transformer? I doubt it but just putting it out there.
