I also have an original W.U. Model 32 Telex machine that I use on i-Telex.  I did the mod change the loop current.  I leave it on 24/7 most of the time.  The outside top of the cover gets noticeably warm to the touch but I have never done anything to try to cool it down.  The board also looks a little "toasty" like yours.  It all seems good.

Hey folks, I recently got my M32 up and running on i-Telex and all is good but things are getting a little toasty and I am not sure how much I need to worry.  Please see attachments - the circles I drew show where it's getting hot.  120-130F if my Harbor Freight thermometer is to be believed.

As there is quite a bit of room in there, I was wondering if a small fan would be helpful. 

Any thoughts appreciated!

thanks

Andy
