You can say that again. What's the inrush current like on it?
That what I hate about the forums. Seeing new equipment you never knew existed, looking at what one would cost locally and suddenly not being able to live without one any more. Ignorance is actual bliss.
Received some HV caps from HFO (Poland) so managed to finish re-capping my old PSU. Voltage rails seem to be within tollerance now so I'm giving the old girl a face-lift with a new alloy front together with 4mm banana sockets (they replace the 2mm sockets that were on the plastic cover - seen lying on the bench). I installed a voltmeter to monitor the output but to have one for each rail would take up too much space so instead there's a rotary switch to flip from one to another. I don't really need to monitor them all the time anyway. There's no current limit on this PSU but I have several others that do, this is a plain vanilla voltage supply.

I don't really have a way to measure that (clamp meter is probably too slow to pickup anything) but it does do a nice "tick" if I plug it in while it's on.
I was trying to see if it causes the lights to dim, but could not notice anything, but I heard a UPS in the other room go on and off lol. It may possibly have some kind of inrush current limiting too.
Try looking that patent up!
Paid 50p at the Kempton Park radio rally... Now I have to find a use for it.
The rotator seems to have three wires... Any clues?
(I wonder if the hand is radioactive?) Seems to be Bakerlite or similar.
I'm thinking the A,B,C wires are windings around a common rotor... each 120 degrees apart.... so I need to generate three voltages to make it point in some direction...
Well wheres all the new purchases from Kempton Park Radio Rally today then? With the exception of NivagSwerdna who has posted with his new purchase from it there's a positive silence on it, I'm wondering if it was a washout in which case I'm glad I didn't go or was it brilliant for bargains in which I'd be jealous as hell of your sweet purchases and mad at myself for saying that it was to far away for me....

There were plenty of people buying things... I saw someone walk off smiling with a very crusty oscilloscope. There was a stand with some interesting old stuff but the stall holder seemed to have high expectations of prices so wasn't selling much. I also saw a lot of people buying heat shrink tubing! And the Rigol-UK man said he had sold a few 1054Zs. (I *maybe* intend to buy a DMR handheld to tinker with... but will use ebay.) Oh and I looked for a 6N7 but couldn't find one. (I was told that they were being bought up at high prices by the cryogenically frozen cable crowd).
Always good to stock up on heat shrink tubing as it fits in to any budget.

It's not too expensive to begin with though.

A handful K-type thermocouples.
I got two additional electrical motor scooters with dead batteries for parts and easier debugging. This is the brushless motor controller, everything is conformal coated :-( i'm trying to trace the pinout of the RS232 debug connector.
Waiting to receive my Tek MDO3014 from TEquipment! Friday can't come soon enough!
I just received one of Franky's surplus mini Electronic Loads: EBD-M02
As usual with Franky, it was a very fast shipping with superb packaging.
In honour of my first 6.5 digit meter I thought that I'd better succumb to a voltage reference to check and calibrate against with it and my other meters
Well now you need a 7-1/2 digit meter to check your 6-1/2 meter is reading accurately...
Well now you need a 7-1/2 digit meter to check your 6-1/2 meter is reading accurately...
And then you will need a 8.5 digit meter to check your 7.5 digit meter. And then.........
Well you never know, they could well be a near purchase, after all I have just gone from analogue to 3.5 digits, to 4.5 and 5.5 and then onto 6.5, well technically I already have a 7.5 digit meter as my 6.5 digit meter is that on the 10v DC range, oh bugger that means 8.5 digits next time, will my bank support that?
Today I received a 1ltr spray bottle of 99.9% isopropyl alcohol.
Another mundane but very useful purchase from Ebay. Make tuning up radios so much easier now.

Put them on on my Aliexpress shopping list for the 11.11

I have a set of those. The tips on the smaller ones tend to break easily.

I like my Brymen probes on my 235 so much I just bought some for my old Victor 90c DMM. It's amazing how much difference the gold plating makes when doing basic tasks like checking continuity.
I shared a table at Kempton Park on Sunday with a friend of mine. The rally was quite busy with more test equipment than usual on offer. Prices ranged from reasonable to eye wateringly expensive stuff. I was offering my surplus test gear as usual & sold everything I brought except a Solartron 7060 DMM. I do mean every piece of proper test kit that I brought along.
Most people there seemed intent on buying IF prices were sensible. I guess my pricing was which is why stuff sold.
My plan was to sell & not buy anything but I failed miserably. I bought a few of the Schaffner filters used on the Solartron instruments for £2-50 ea. These are always failing & really expensive new. I also bought 3 large boxes of assorted ICs. My guess is ~500 tubes - most part used - but still a potentially useful collection. Apart from test gear I also collect semiconductors an the basis that these will be very useful one day to repair something. The car was almost as full coming home as when I left. At least ICs are easier to store.
