Melted small transformer on mep 005

I just received my 4 mep 005s. One has a small transformer it’s a small black rectangle with one set of wires wrapped thru the hole in the center of it. It’s totally melted into a puddle. What could cause this and where can I buy one. I don’t see any on eBay
I am also missing a hertz gauge, does the 005 use the same hertz guage as the mep 002?
Thanks for any info guys?
Anyone parting out an 005? If so pñeaE let me know. Thanks again

Have you ever heard of using a parts TM?

I don’t have one. I only have the repair manual Tm right now, and I am on an island which has weak cel signal so the odds of me successfully dowñloading a file that large aren’t very good.
I was hoping to find someone with an 005 they are parting out, thanks
