Oldest, working test equipment

Post by tunneldiode » Sat Sep 17, 2011 12:46 pm

Sideband's Advance SG  thread prompted this question.

What is your oldest item of test equipment that is working and still in use?
Disregarding museum pieces; it has to in working order, and something that you still use.

Most of my test gear dates from the 1970s (Tek, HP, Gould/Advance, Data Precision, Fluke, Marconi) so, like a Dragon, I'll have to declare myself 'out'

1945 AVO All wave oscillator
1947 AVO valve tester
1947 AVO 7 Multimeter

I have to admit that I have mainly stopped using the AVO sig gen now in favour of a 1960's All transistor jobby the Nombrex 27. The AVO 7 is used less and less.

So I guess The valve tester is the most used, which is at least 2 -3 times a week.

My 1958 Greyhill Instruments CR 50 bridge (with Magic eye and leakage tester). I had to replace a 1M resistor recently. Apart from that I think it might be original. Someone might have replaced the mains flex in 1970s, not sure.

I guess someone has something made by AVO in 1923 that still goes? That's the oldest I expect to hear about.

Like "tunneldiode", most of my gear is from the '70s. I happen to think that the 1970s was a golden age of analogue design; it was before ICs were in widespread use, and those that you tended to see where fairly standard and easily obtainable or substitutable today. Designers then had to know how to use transistors, and the subtlety of some of the designs is amazing. So I guess that I'm not much help here.

Anyone know when the Telequipment Serviscope Minor dates from? I think that's the oldest I have, and it gets used now and then - never gone wrong in the 20 years I've had it. My son took it to pre-school when "O" was the letter of the day - I had to supply a note explaining what it was. (When it was "R", he took a Red Roberts Rambler Radio :D)

I suppose that the Advance genny is the oldest bit of testgear and still in fairly regular use. I also have an Advance type 63 but as that is AM/FM I assume it's a bit later than the B4A.

I should have said in my OP, that pictures shall be provided! (Pretty please!) :)

How old is the Taylor 45B valve tester as I have one of those?

I thought the B were mid to late 1950's

..in which case it might just be slightly older that the Advance genny. I'll see if there's a date somewhere.

I love that old AVO kit; they seemed to keep their WW2 styling until the 1960s.
