How can I tell if my amp is really a ms-2250?

stevesteve703@live.com · Sat Jan 28, 2012 7:13 pm

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.

stevesteve703@live.com · Sat Jan 28, 2012 7:53 pm

serial number sticker is not on the back cover, is it anywhere else?

MS2125 or MAC500. I need rail caps voltage

wooferdog · Post by **wooferdog** » Sun Jan 29, 2012 4:49 am

number should be on the board inside on a white sticker. can you get a better pic of the inside ?

Post by **Eric D** » Sun Jan 29, 2012 7:59 am

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.

Rail voltage? how do I check that?

thats the same rating as my original ms2250

stevesteve703@live.com · Sun Jan 29, 2012 10:04 am

So I can assume the guy I bought it off is telling the truth? it is a ms-2250?

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

stevesteve703@live.com · Sun Jan 29, 2012 10:56 am

Doesnt have anything on the board that would give it away.

What´s the part number on the 2 bigger transformers?

Post by **Eric D** » Sun Jan 29, 2012 11:26 am

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).

wooferdog · Post by **wooferdog** » Sun Jan 29, 2012 11:36 am

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.

Im not sure what to look for

looking at the feeds from the coils i would say its not a ms2250

Valeks1 has been working and repairing pg amp for amost 20years i would say he would know the best

Yep, sure does look like a MAC500...

Cant find any info or specs on a mac500......
the transformers(?) look a bit different on mine I think

Parts# can be 9005.0029 and 9005.0030 or 9005.0029A and 9005.0030A

Specs same as MS2250TA
