This 1541 "C" disk drive for a Commodore 64 was sent in by a customer for repair, as it was no longer reading diskettes.
A short bit of troubleshooting showed that one of the coils on the R/W head was "open" and no longer able to read. I sourced a replacement head and install it, then proceed to do a head alignment procedure and thorough testing.
The drive has been back with the owner for a bit now and working great!

I am NOT an expert, I have genuinely NO idea what I'm doing, and mostly just glue things together and use a lot of Google-fu until stuff works. I've been tinkering with electronics since I was a kid, but have no formal training and will probably do things incorrectly. If you learn something from this, that's awesome, but trust me - I'm learning too!
