Discuss Old test equipment, from when Pete was a boy! in the UK Electrical Forum area at ElectriciansForums.net

Not electrical but radio. This simple signal generator needs some work, but is still incredibly accurate. It is clear a lot of work has been put into the design. My modern Keysight is very clever but far less interesting to look at inside. I have a few other sig gens with some rather fancy tropicalised components.

Chuck the meter. The little wooden box will be great for sandwiches.
As said earlier - philistine ;)
Love these old test meters and similar calculators, slide rules et-cetra. I'm after one of these but prices are rapidly passing that of a new Megger A NICE CURTA I CALCULATOR IN A VERY GOOD CONDITION | eBay - https://www.ebay.co.uk/itm/A-NICE-CURTA-I-CALCULATOR-IN-A-VERY-GOOD-CONDITION/303050404546?hash=item468f3632c2:g:mhcAAOSwv0tVWLOf:rk:5:pf:1&frcectupt=true
 
pencil and a set of log tables are cheaper.
...and do wonders for the understanding of maths. I sat in college with lads of all ages who just could not get their head around Ohm's Law. Could not manipulate or re-arrange it after a year of using it. Fortunately, dad was a spark and they got well paid jobs for which I carry no bitterness what soever ;)
 
I'm in the process of moving house and came across this today. Somebody gave it to me from a house clearance a few years ago, thought it might be of interest.View attachment 48042
I like the Dynomometer

I like the Dynamometer, can be a very useful piece of kit if you want to measure the true power consumption of something that has a non unity power factor. I have used one in the past when checking the power consumption of one of my designs.
