CJ MF2550 Replacing the power amp fuss


Hi All
It looks like the fuses on My CJ MF2550 power amp have blown.  have ordered the replacements (after discussing the issue with Jeff at CJ) and hopefully they will arrive soon.
I was wondering if anyone has replaced the fuses in this app before. I wanted to know if all one has to do is to unscrew the bottom plate to access the PCBs or does it require more work to gain access to the boards.

thanks

Yes; you’ll be able to replace the rail fuses, by removing your bottom plate.     Of course: unplug the amp, first.      
You have to order the fuse? What kind of fuse is it? I'm just being noisy.

I've ordered in bulk.  I saw a guy selling bussman slow blow 4 amp fused for 170.00 a pair.... I payed under 60.00 for 30 fuses. Bussman fuses too. Granger... if I recall.. I whipped up the graphene, paint. 50/50 graphene/nuclear never seize. 

Nickel, copper, lead, aluminum, calcium oxide, graphite and  GRAPHENE
The paste is good for 2200 degrees F, and 500 degrees F before it will drip...

Please tell us how you blew all the fuses?  I had a MF2550 (I didn’t care for it) for 8 months or so in 2017 and never blew fuses. The interior build quality of the CJ is very high.  Did you have a dead short or something?
Not sure yet how the fuses blew. The MF2550 was connected to a CJ ACT2. All was OK until I switched the source of the ACT2 (went from AUX to CD) and I heard a loud pop and the AMP stopped working. By that I mean the output volume was very low. Even when I connected  a source directly to the AMP (no pre amp) the volume was low but clean at low source volumes but started distorting as the source volume was increased.

A quick update. Replaced the fuses. It was very easy to so so.
Just as an FYI so it may help others in the future - The bottom plate has to be removed. there are 18 screws that have to be removed and once you do that the plate comes right off.you can see the fuses immediately. There are four of them two for each Channel.swap them out and you're good to go.
thanks for all the support
