[GreenKeys] How hot is too hot? (Teletype 32)

[Paul Heller]

Nice machine!

A fan is an interesting idea. A small one that runs off 120vac perhaps. 

I don’t have that insulator in mine and I think Wayne’s suggestion to remove it is a good one. I often leave the lid opened to let air circulate in there. 

It seems like a bad design. The European machines have a relay which is much better. I don’t know how they dissipate power from the small amount of loop current when not in a call, but I’ve not noticed heat build up in them. Yes it gets pretty warm and I often worry about that but so far all is doing ok on my machine. I do power it off when going away for any extended amount of time.
