Wetherby is my home town sandbank industrial estate I worked on them in 1988 first job was to wire the heatsink I always remember the grey wire melting lol
I bought a Farnell twin meter power supply I think of similar age. I downloaded a wiring diagram and instruction sheet. I have used it almost every day for 10 plus years. They are such a quality build top class components mine also is very accurate and as you have demonstrated they are designed to be easily repaired! My same thought that you need more than one P/Supply I have started looking and was nearly tempted to by cheap digital unit, but thank goodness I watched this video! My plan is eBay Farnell unit again. Enjoyed vid as usual thank you.
Good morning Bill. I must have had my Farnell PSU type L30 for about fifteen years now, bought from Ebay. I can't remember how much I paid for it, but it's still working very well.
Yahey! I've got one of these... it's my main lab power supply! Back in the 80s, the company I worked for got most of their components from one incarnation of Farnell or the other. A curve tracer would be ACE.... gotta look round your channel, see if you've got any details.
Great video. With the multi-function component tester you are using, a zener diode must be connected between A and K. If connected between any of the numbers, the voltage won't be high enough to show its a zener diode. Of course I don't know what the red and black sockets are connected to and the diode may be faulty, but I thought it's worth a mention.
Nice video and explanation of what you were doing. Could you do a video explaining what to expect from curve tracer for different components and what is good and what is bad or ready to fail if that is possible. Most videos I have seen they assume everyone is an electronics eng. and whizz through the video not explaining properly, many thanks again. I notice you have North Yorkshire I live in Redcar.
Just bought 2 of these for £20 at a car boot. They seem OK. I searched for info, and found your video. I also found a manual, including schematic. Would you like it?
I hate these dual range buttons. Wonder how many times someone connected something and destroyed it because they thought they were on the 0-15V range when it was really switched to 0-30V.

There built like tanks , I bought one at a radio rally for £10, restored it, and it been working well for the last 5 Years.
Gray wire on the heatsink first wire I fitted professionally in 1988 .......and melted lol 😆 happy memories 😊

Great work,,, and love how they designed it. You can tell they were thinking.
Great video as usual Bill, yes Farrell was a favourite of mine back n the day and followed its various manifestations over the years. Happy New Year

Good work! Thanks for the video!👍🏻 Like from Belarus.

Excellent, thank you!
Tried it, and yes it correctly identifies the zener and it's voltage.
£15.00 !! Nice deal. :)

The blue wire is ok to use. A bigger wire will draw more currant causing fire. 💡🎙🚒
Don't you need to shorten the scan line on the curve tracer so both sides are on the screen to start?
My scope won't let me shorten the line, however it was centred using the X-Pos control and the line ends were only just off the edge of the display.
be interesting to see the ripple it puts out under load...
