content: I stumbled over a large collection of old test equipment today. A family was selling the stuff after a guy that had been collecting various bits of things for the last half century or so (Bjørns Samling). Most of the test gear came from a TV repair company that closed down in 1989 or thereabouts, and I ended up getting some of it. This was the biggest collection of vintage gear I've seenTaylor 65b Signal generatorPhilips GM2892 TV pattern generatorLeader LFM-3610 WOW and Flutter meterOld wattmeter, ended up getting this because of the nice caseCustom thing, quite large, no idea what it doesLeader LSG 17 Signal generator, LMV182A AC Millivoltmeter and 8 ohm 50W resistor.

Got a nicestereomicroscope as well

content: That "ancient multimeter" looks to be an Avo 7 or 8 (I'm sure someone will come along and correct me in a minute). They're actually very good, well made instruments and I still find use for mine fairly regularly.

content: Quote from: richard.cs on June 13, 2015, 09:55:40 pmI think it's an Avo 8 mk5. Great meters when they're working, perfect for measuring very high voltages and still good for low voltages so long as the 20,000 ohms / V meter doesn't affect the reading too much. Typically still better than the spec'd <3% accuracy years after they were last checked.

content: That is not actually a stereo microscope. It only has one objective lens. It is a binocular scope only, but still nice to have.

content: Quote from: Lightages on June 14, 2015, 06:41:26 pmHmm, good to know. I've only used microscopes with one eyepiece before.The signal generator seems to work, but the selection switch is a bit dodgy.
