				I am missing the side plate and was told it is a 2250 but it looks the same to me as the other models. is there anyone that can guide me to the differences, I have a ms-2125 for comparison

				what is the serial number on the board ? Should start with 22 if it's a 2250.

				MS2125 or MAC500. I need rail caps voltage

				The transformers are too small to be a MS2250, MS2250TA, or MAC500.
I am guessing it is a MS2125, or a MPS2500, but only the rail voltage would determine that.

				Is there a decal on the circuit board of the amp that has a number on it?

				At this point I think it is a MS2125 which someone installed MS2250 caps in.
The transformers are not big enough to be a MS2250 (those in there would saturate).

				the number should be on the right side next to the ps caps if you have the amp upside down and the wiring side facing you.
