It's a RIM Oszillette. RIM was a shop/seller in
Munich that was widely
known to sell interesting kits, mainly in the 60s/70s. They sold
electronic parts, amplifiers, power supply etc. and many things as a kit.
One of the kits was the Oszillette, a small scope with a tiny Valvo scope
tube and only 4 or 5 other valves. We have it on the picture to show the
difference: tiny 5 valve scope compared to huge over 100 valve scope (plus
external power supply), as much as in our LGP-30!
The Oszillette has no trigger, it's free running with sync and frequency
adjustments via front knobs, and only 1:1 and 1:10 signal inputs.
Christian,
it looks to be a neat little unit!
I have a couple of small scopes, for example the Cossor 1039 here:
http://www.g1jbg.co.uk/test8.htm
which has three valves as well as the CRT, and was intended for TV service.
I also have a Muirehead frequency comparator, which has a 1" CRT, a crystal
oscillator and a simple Y amplifier, and is designed to compare external
frequencies with one of three switched crystal references, using Lissajou
patterns.
I have a few large Tek scopes (585, 545A, 545B, 547, 541, 535A, 515A and
502A), as well as a couple of later models (561, 564, 564B and a 647). I
find the big old original 500's easy to use and easy to maintain, my
current scope of choice is the 535A. The later 560 series are more
difficult to maintain, but are more convenient in the workshop. What I'd
really like is a 549, if anyone with in a 100 miles of London has one they
no longer want :-)
Jim.
