" I'm assuming it must be round.. although directly under the fuse is a little black box connected to it. I note when I plug it in on Line sometimes there's a single metallic clack from the PSU area and sometimes it's multiple..lioe someone's operating a telegraph."
The start/run caps can be tubular, rectangular or 'bathtub' shaped. Again, this is just generic advice and I can't say which shape(s) were used by TTY Corp. As for the one clack vs. telegraph-like clacks, that sounds an awful lot like a relay or solenoid that sometimes acts OK, and other times, sits there fluttering as it lacks sufficient current to pull-in or hold the relay armature. Bad filter caps in a DC supply (to the solenoid coil..) is classic for this. Ever seen a one of the cheap, obnoxious 120 AC buzzers they used in old stoves and so on, as a "done" signal? They're just an AC relay designed such that the coil cannot hold the armature between cycles - so it just buzzes like mad to alert you to the status of yr Pizza rolls. =P On Fri, Oct 14, 2016 at 1:46 AM, David Collins <[email protected]> wrote: > You might want to try moving the keyboard forward and away from the > operating lever that connects to it at the back right corner of the > keyboard.
