Now I have two... one more and I believe I qualify for addiction counselling.

Uhhhhhhhh so today I bought all this stuff for $50. The top looks to just be an oscilloscope, middle layer is a more modern motor tester (90s?), which has a lot of serial ports on the back, and also there's some kind of memory card slot or something on the front. The presence of a keypad makes me think this one will probably have some kind of software on it, note it also lacks an X/Y joystick so to me that suggests the display will have a raster output which again suggests it will be some rudimentary digital computer.

Bottom row left to right we have a printer that takes receipt paper and appears to connect to the unit above it, YET ANOTHER MOT-201, and an 007.001 vacuum/pressure tester.

The vacuum/pressure tester is in pretty rough shape and the hose barbs are all broken off and the dials are seized. Still, it is essentially just some gauges and some valves so I will see if I can get it in working order.

Everything else seems okay.

Okay, more updates.

I tore down the 007.01 vacuum and pressure tester, cleaned everything, fixed one of the gauges, and reassembled. The barbs on the front (under the ports A, B, C, D) were all snapped off. I found some stainless steel replacements in the right size so am just waiting on them. Otherwise the unit is working great, and the gauges agree with my other vac gauge. The internal pipes had a bunch of contaminants in them, I flushed it all out. The valves were sticking so I basically flooded them with WD40 and worked them until they came free, then I flushed out the WD40. Everything works nicely now.

Very cool James! I love buying and fixing old tools aswell.

Noticed your slight mods to your drill press, grab a treadmill motor when you see them in council pickup and build a variable controller for it

      Interesting idea!

        I got this Bosch MOT-401 working. This is just an oscilloscope, basically the left half of the MOT-201. This one is newer, the internals are much more sparse and the layout is more modern. I tested a bunch of resistors and caps and everything tested OK so I fired it up and it appears to work. I haven't hooked it up to a running motor yet.

        The silkscreen in front of the CRT was damaged so I took one from a spare unit (one that is only good for parts) and installed it. Win!

        Okay getting pretty close with this unit. Still having trouble with the ignition cut out function but got everything else working.

        ^ hooked up to an LH-2.4 240

        Hi james,

        that repco / warren and brown valve spring tester - if you contact warren and brown they can happily recalibrate it for you.

        i work for NAPA autoparts, one of the many GPC companies inc Repco.

        Okay it's been ages but

        Top unit - repaired, will probably remain my in-service unit in the workshop as it's overall in the best condition.

        Middle unit - roughest aesthetically so it has been sacrificed for parts

        Bottom unit - this is the very first one I acquired - still a WIP. I may or may not just scrap it, the parts unit has a good transformer but I would still need to spend about $70 plus hours of my time to re-cap it. If they were worth a few hundred dollars I'd do it but I've been buying them for $50

          jamesinc Hi James, I am new to the forum and was hoping you might be able to assist me with some parts for a Bosch 201 that I am fixing. My unit has a bad diode on the rectifier board (Siemens E1105). Would you have any in your spares that you would part with.
          Cheers,
          Graeme

                I am teaching at TAFE now, mostly at Cowra and Orange. Today I wheeled out an old Mot-201 that was stashed away in our Cowra workshop and fired it up with the students on an old red 202. Seems to be working ok but couldn't get timing light to function. Did you figure yours out @jamesinc?
