Hi, I take a few internal photos of some instruments

APPA703, LCR metter with basic accuracy 0.2%, 4W measuring, 100Hz-100KHz

Wow that japanese scope has a really sharp trace. Also like the really long shaft extenders for the intensity, focus and scale illumination potentiometers.

The Czechoslovakian scope has a reason to have such a small CRT. It's much easier to increase the writing speed of the CRT by just reducing the size of it.

Welcome and thanks for Great photos!

Thanks for the nice pictures.

I especially like the Tesla scope. Looks very neat & tidy inside.

Now I know where the green resistors with printed on values - of which I got a 1kg bag in ~1993 - come from .

Yes, these green resistors like TR191 TR192 etc were produced in Czechoslovakia by Tesla.
They are low inductance high stable types, but when you are soldering them too long, they fall apart .
