Just stumbled across this while looking for other stuff... Not sure if $6 ea plus $6 shipping is overall a good price for fleaBay as I'm rarely searching for resistors of such low tolerance (I know reel end lots can occasionally be had for a steal), but DigiKey's 1/ea pricing is $US15-50 for similar from Vishay Precision. Also they're coming from the UK, so may be a boon for you of the tea & biscuits crowd.

No, not the UK, from Poland. I've used these people a few times and indeed used a few of the low values of exactly those Sfernice resistors to repair the bottom two resistors on my Vishay precision decade box. Fast, reliable and definitely selling genuine stock. I'm close enough to volt-nuttery to be able to confirm the values of high precision resistors and the ones from them were all well within specification (including tempco).

I had a few 2K resistors from this line, from this seller, turn up today. i've used them a few times and, while not as close to volt-nuttery as most here, everything bought from them that has been checked has been well within spec so far, and the service has been consistently good. I tested the 4-wire Ohms ranges on my 3455A with resistors from them, against a GDM-8341 with a 6-month old factory cal, spot on. I have a plan to collect enough low-tolerance/low tempco resistors to eventually improve an old decade box with really nice switches that I have, so it's good to hear of you already doing that.

Yeah it’s a DG1022Z. Got it from Telonic...

Had some spare cash to burn due some financial kismet so I bought another Rigol AWG this morning as I need a very frequency stable IF signal source for something and it is the cheapest even with the problems. Phase noise is a bit pants but it will do. Should get this tomorrow if DPD don’t fuck up. Also found a complete blithering idiot seller on eBay who has no idea what they are selling and keeps under pricing things which are trivially broken. Unfortunately nothing interesting available today as some other people are floating around them like flies around shit. I’m not linking them here or I’ll do myself out of toys and profitable fix ups (sorry all >:D )
Anyway I’m going to bed in a sulk because I feel man flu coming which means my new toys are all going to get covered in snot.

Hold on, you sold your Rigol oscilloscope and AWG not too long ago while and now you bought both again? I don't seem to remember you being very pleased with them last time.
bd139:
I’m not really. But they solve a class of problems I admittedly have and can’t solve with the analogue only kit without eye gouging pain. Didn’t make much of a loss on it so :-//
I can’t justify a £3000 outlay for equivalent Keysight branded stuff for example.
One big improvement recently is a workspace I can use them effectively on which makes them considerably less frustrating to use.
Specmaster:
I was looking at a Fluke 8840A bench meter the seller is asking £150 for, supposed to be in excellent condition. Anyway after asking a few questions about it I asked for a photos showing the display working., fair enough given that these have high failure rates.
It transpires that they cannot provide a photo of it working as they don't have the mains cable :wtf: and yet they said it was excellent condition and valused it at £150. I explained that it is a standard IEC lead, possibly same as the lead fitted to their TV so they took a photo of the back of the meter and sent that to me saying that didn't have the lead, just as well they did that, because it turns out that it doesn't have the AC volts Option 09 fitted, and no test leads either. To make it even worse, it is well out of calibration and has a warning written on it stating that as well.
So just how the hell did they value this meter at £150 when they don't even know if it works, what the display is like, and didn't even know that it couldn't measure AC volts :palm: :scared:
