I could desperately use some good photos of the inside and bottom PCB's and wiring on a MF2300A or maybe the MF2300 would work. Whoever attempted repairs before i purchased my unit had everything mixed up as well as many Transistors replaced with units of incorrect values. I desperately need good ,clear, bright images of the top and bottom with the panels removed , need good enough images to determine the wire marking where the cluster of wires connect to the board. I'll be happy to contribute the official schematic for the MF2300A as i see there is good call for it here ,I've not released it elsewhere as of yet.
Happy to be part of the community and hope i can contribute as much as i receive. Mark

I think what you really need are the schematics. Unfortunately, we don't have this particular unit's schematics in our database yet.
I did some googling and this is the best I could find in terms of pictures: https://www.gzhifi.com/ls/goods.php?id=2377
Let us know how it goes.

Cheers, but i already have these. no shots of the bottom and all the psu wires have a coating on them so i cant see the color coding. I have the europe export edition MF2300A 240v, the unit has its inputs split left and right like dual mono design with individual vampire wires leading from each primary board directly to the rca inputs. i cant even find a photo of one with this configuration. none of the psu wires were connected when i got the amp, thats the main thing i need.

Here are some photos of an MF2300A. More (and sharper) photos to follow, soon.

Hi Mosfet. Nice photos.
From that IMG_4016.JPG image, are those larger upright black electrolytic caps with the black tops bulging on top? It is a bit difficult to tell from the image but looks like they might be. Bulging electrolytics could mean they are in bad condition. If this is your amp and they are bulging, you might want to consider getting them replaced. It could help you avoid a more expensive failure down the road.

Thank you, plurn. I acquired a complete set of replacement electrolytic capacitors earlier this year. Now, to find the time to install them...
