Is this a 2250?

Post by mitchwolos »

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?

Based on the serial number it’s a mac500. What does the endplate say?
A few of these and a few of those.
