Andy Woods Posted November 2, 2010 Report Share Posted November 2, 2010 Fond memories.... Started off using one of these beauties back in a former life when I used to be a TV repairman....! Anybody else remember hybrid Decca Bradfords, G8-550's, Dorics, Thorn 300 chassis..... My old boss used to light his fags by wrapping a rizzla paper around a long screwdriver and then short from chassis to the PL500 valve top cap...big blue spark! Still have my AVO MK7 on the boat today...somehow seems wrong to part with it and it's still useful. Link to comment Share on other sites More sharing options...

carlt Posted November 2, 2010 Report Share Posted November 2, 2010 This is mine For our practical work, we used a black box mystically called an "AVO". Why "mystically"?? I always thought the origin of the name obvious... Link to comment Share on other sites More sharing options...

Ray T Posted November 2, 2010 Report Share Posted November 2, 2010 Used to use the things at tech college and work. Never really understood them. Didn't like electronics, surprising then that I was employed by GPO / Post Offce Telephones / BT for 42 years!! Link to comment Share on other sites More sharing options...
OldGoldy Posted November 2, 2010 Report Share Posted November 2, 2010 Fond memories.... Anybody else remember hybrid Decca Bradfords, G8-550's, Dorics, Thorn 300 chassis..... Thorn 300 chassis? Do you mean Ferguson 306s & 308s or do you mean 3000/3500s? Giving my age away now! Vintage TV porn HERE (safe) Link to comment Share on other sites More sharing options...

U/G Lead cables and cups of tea Seriously though, I did 35yrs too (in Brum) Mainly PABXs (planning, commissioning etc) but if I remember correctly, our meters were Taylor.

WotEver Posted November 2, 2010 Report Share Posted November 2, 2010 (edited) Nice one, Richard It's an older model than mine, but then I have had mine since new (no leather case though, I couldn't afford that as well). You'll almost certainly need a new 15V battery and you can get one from Maplin. The other battery is just a D cell. You can get original test leads on Ebay but they generally go for silly money - up to £30 a pair. Seeing as how the test lead connectors take standard banana plugs I'd go for something more contemporary such as these from Farnell. I'm sure there are cheaper offerings around. Here are some instructions. And here's a circuit diagram Tony I bet the ohms per volt figure will be better on some of my sub-£10 meters than on your new purchase. 20kΩ/V as i recall, for an Avo 8. I have one of these.... ... sat just by me here - can't bring myself to let it go. Is that an Eddystone?

On a different note I do still have my Weston IV and weston V lightmeters I have the cardboard box from my Weston Euromaster in front of me. No idea why it's here Used to have a III, dunno what happened to it. Tim Link to comment Share on other sites More sharing options...
Phil Ambrose Posted November 2, 2010 Report Share Posted November 2, 2010 Yes, I found out on Saturday night that this means everything to some people, and nothing at all to others. I have another of these cultural icons that produces the same reaction with a different group of people - a Machinery's Handbook (seventeenth edition) Richard I guess the box of slip gauges is the same Oooh Machinery Handbook afraid I had to give mine away to a good mate as moving from widebeam to NB meant somethings had to go, mine belonged to my Father dated circa 1939, and I was still using it upto 1981 when I left Engineering (sorry chaps we can get it made cheaper abroad)and the number of times I've thought "if only I had some slip gauges" Phil Link to comment Share on other sites More sharing options...
Giggetty Posted November 2, 2010 Report Share Posted November 2, 2010 An Avo 8 mark III - an ebay bargain. I just need a set of Avo leads and probes now Richard For the resistance range you'll need a 15v battery. I've had some difficulty replacing mine.

NB Willawaw Posted November 2, 2010 Report Share Posted November 2, 2010 (edited) Yes it uses a 1.5V battery and a 15V battery for the higher resistance ranges. The 1.5V battery is a strange shape/size as well (anybody remember Ever Ready U2's), but I've got mine soldered to the wires.

RLWP Posted November 2, 2010 Author Report Share Posted November 2, 2010 Thank you. That has been very helpful. Adrian I can't claim all the credit for that. I have two friends who are AVO fanciers, and one of them is trying to persuade the rest of us to make a bulk buy to get a lower price Richard Link to comment Share on other sites More sharing options...
