Hello,

This is my first post to the list, I have been active on rtty via MMTTY for sometime and have finally now acquired some real hardware.

An estate sale locally turned up a Kleinschmidt TT-4C/TG for A$50, one of five once owned by an ex Telecom Australia employee. The other four went to re-enactors & museums. There was mountain of other scrap tty gear and other ham radio stuff, plus apparently 2.5 tons (!) of teletype paper that went to the dump before I got there.

The TT-4 is in aboslutely immaculate condition, and as far as I can see, has had next to no use at all. When I popped off the immersion cover the smell of the fungicide nearly knocked me out. A plate fastened inside stated it was supplied by Amalgamated Wireless Australia (AWA) to the Australian Army, in 1976.

I quickly built up a loop supply and a terminal unit (from the design by Eric Volpe using a 2211 chip) and hooked everything up to ITTY. After a bit of fiddling around (adjusting the motor speed using the tuning fork etc) I started getting perfect copy.

So now a question. I have downloaded the relevant technical manuals for the TT-4/C including the service manual TM-11-5815-206-34. Unfortunately all the photos/diagrams are unreadable, completely black at worst or with the numbers of the lubrication points visible but not the points themselves at best. Does anyone have readable scans they could please provide me with?

I would like to check all the lubrication if possible before I use the TT-4 too much. Thanks very much.

Also a big thank you to the provider(s) of ITTY for providing me something to demonstrate the machine with.

I attach a photo of the TT-4 as received standing on the floor of my garage. All the tapes were still tied around the keys and all the variious keyboard and platten locks were in place as described in the user manual. The power cord was still wrapped in brown paper. The spare gears for 100 wpm were all in place, as well as the spare fuses and the tuning fork.

regards
