I have a bit of an oddball 2125.
Serial 500012
It has 6800uf 63v rail caps that appear to be original. Rail voltage is 50/51v. Red toroids 9005 0030/29. They're definitely thicker than all my other 2125s and it has irfp054 power supply fets.
All my other 2125s are 37-40v rail voltage.
It also has 3 resistors in series at R345 and R346.
Has anyone seen something like this?
Is this a 2250?
Re: Is this a 2250?
Based on the serial number it’s a mac500. What does the endplate say?
A few of these and a few of those.
