Watching my CTC-4 right now. I left it unattended for a couple of hours once, then thought about what I did.

Now I won't leave it for more than a couple of minutes, and even that seems too long.

Great chassis, in super condition, with very low hours when I got it, but these precious old relics can't really be trusted the way they could have been when they were new. Same with the B/W sets in the collection.
