Holy shit. I was searching the forum for this. The exact same thing happened to me!

I have a 2125 with 63v rail caps. IRFP054 fets. 51v rail voltage. 500012 serial number. Looks like the same toroids as me. 9005 0029/0030

I have a bit of an oddball 2125. Serial 500012 It has 6800uf 63v rail caps that appear to be original. Rail voltage is 50/51v. Red toroids 9005 0030/29. They're definitely thicker than all my other 2125s and it has irfp054 power supply fets. All my other 2125s are 37-40v rail voltage. It also has 3 ...

Also, Which rail caps are you guys using?

I'm getting started on my build soon. It's going to be a 16ch active 6.2 upmixed system (2 Alpine F1 DSPs). I have a big stack of MS/MPS amps I'm going to use. 9 in total for this build. 3x MPS-2240s (Front/Rear/Front and Rear Center) 3x MS-275s (Front/Rear/Center Midrange) 3x MS-2125s (Front Midbas...

Hi guys. I've recently given my friend one of my spare amps (ZX450) and am using it to run components active. But the processing is done before the amplifier. There is a slight engine noise intermittently. And I would like to bypass/remove the crossover board. It has some corrosion on it and all the...
