Hi CJ Friends. Can anyone get a hold of a schematic for the MF-2275 SE? Or would anyone be willing to take some highrez pic of inside of there SE and post them here.

Much appreciated!

Sadly, they’re or there, if it’s not in the database, it’s not here.

Of course I know you’re hoping someone can take a high res photo, but if the 2275 is like most modern SS gear, its PCB is multilayered.

Better to take a picture of yours and share it here. Maybe someone will notice a bubbled cap or burned out resistor.
It’s just stuff. I like mine. I hope you like yours. I probably like yours too.

Hello!
No issues with the amp.

My MF 2275 is non-SE version so im planning a DIY upgrade project for it and wanted to see the areas and values for the upgraded components CJ used in the SE version. I've found a couple of pics on line and can see location of the Caddock TF020s but would like to find the feedback resistors and few other details. If anyone is interested in collaborating on this let me know. :D

Well whatdya know... The MF2275 I purchased arrived today. Audio seller with lots of positive feedback. Basically dumped in box with one wraparound of thin bubble rap floating around in a couple hands full of foam peanuts. Crushed box resemble a snowball after Fedex left if on my porch. Surprise its actually undamaged. Loose RCA plugs (easy fix) and to top it off its actually an SE model. Seller sold it a standard 2275. Lucky Me! Throws a wrench in my plans however. I had been looking forward to getting a non-se and upgrading it is some film and foil caps and zfoils or AMRG resistors. But since this one is already an SE its full of Caddocks (TF020!) and Teflon caps! Hard to want do anything more to this fine amp. These are VERY high build quality on the inside. Very impressive. Sounds very nice compared to my Pass Aleph 3 too! Now I'm not sure what to do other then listen to music. shucks...

Great news. Congrats on the free SE bonus! Glad nothing was damaged with the suboptimal packaging.
