[GreenKeys] UGC-74A Rebirth

[Larry Tighe]

My UGC-74A is slowly coming back to health.


The 74A was not the preferred TTY....the "B" model seems much friendlier....no revolving drum and 88 little hammers beating on the rotating drum.

I had stuck hammers and was pumping cleaner and WD 40 into the stuck ones hoping to free them.  No good.  Finally took the entire hammer assembly challenge....removed some of the cover panels and it turns out there are 4 hammers on each of the 22 similar cards...a piece of cake job.

I pulled all of them out, cleaned the mechanicals with paint thinner and now they're working perfectly.  The paint thinner seems to have cleared out the dissolved infamous platen goo.

It seems this machine will now be dependable and do what she was designed to do.  I think the 74A does have potential and should be a lot of fun over the years.  They are definitely salvageable after the platen "melts" :>)  Please don't junk them anymore ! ! ! !
