FS (GER/FRG) Keithley 182-M (!, read) Nanovoltmeter

[acbern]

For sale is my Keithley 182-M nanovoltmeter. This is NOT an ordinary 182 nanovoltmeter, but a special version (M from military?, I did not find details), incorporating a std. 9V battery to power the first amplifier stage for reduced noise. This is how it came from factory, as one can tell opening it up. I did also own a normal 182 (sold that some time ago) that allowed me to compare internal circuitry and mechnics. The comparison also showed that the peak to peak noise of the 182-M was about half (!) of that of my normal 182.
Selling only as it is sitting arround, since I use other gear.
Selling with custom precision cable (circular connector with Kapton cable and gold plated copper spades) and a custom shorting plug (circular connector with internal short for zero calibration). That allone cost me 100+.
Asking Euro 600, way less than I got for my standard 182 that I sold without a cable and short.
If interested send me a PM. Shipping within EU only. Item located in Germany, pick-up preferred.

While you still have it, could you do a teardown and post some high-res photos of its insides? I would be willing to bet that there are many people here (including me), that would love to see that.
