... Only this time I'm greeted with no trace and the smell of something getting hot. Not again!
Enabler mode: ON - you need an IR camera ...
True, this seems like an obvious use case. Of course with all those hot valves around you're not going to get away with a bottom of the barrel low resolution model, you're going to need to be able the differentiate the fault from a filament. So the obvious choice is a secondhand one, possibly in need of some restoration. So ...
I had a fight with gimp regarding this Sisyphos Tekscope (I have used the 547).
Here are the results:
Difference is the lettering, EEVBLOG vs. EEVBlog
I created then a version with a transparent background and uploaded it to spreadshirt.
This is how it looks on their preview on their website (I do like the grey background):
If somebody is interested, I can upload the xcf files from gimp.
What do you think about this result? Any suggestions, comments, improvements?
@bd139: I did not convert it to a vector graphic image, because I don't know how to do this.
Nice job
Sooo where do I buy one?
Started packing. lugged 6 DVD racks downstairs today (of the 2.02 m kind) and need to get to my taxes later tonite.
Started clearing house. Lugged ~250kg of vinyl LPs to auction house.
Some good points.
I contacted Mirfield and they have already replied saying they will send another unit out and to keep this one. They think that their supplier has thrown a few bad ones in to make up numbers. They apologised and are running self tests before sending them out now apparently. Now I know there is a probability, based on reading the group, that there are ones with modified firmware to pass the self tests so I will DFU the official firmware without such mods onto it and check it works then to make sure I'm not getting screwed. This might be a genuine issue at this point. Time will tell.
I do have to give a thumbs up to Erik at tinySA who has quite frankly amazing support and so far the Mirfield turnaround is minutesDFU both units and then you might end up with 2 working ones
Just remember... "DFU mode" means DON'T. FUCK. UP. Or you may wind up with a nicely decorated brick.

Actually, STM32xxxx are remarkably hard to kill... but man, you can spend days pulling your hair out fixing one that's stuck in zombie mode...I always get a little scared doing firmware updates, really need a UPS for safety’s sake but hey those things cost some serious money.
...Can anyone recommend a 4-wire kelvin leads/clips set with banana (safety OK) plugs? Looking for something dirt cheap, around USD25.
My recommendation for Kelvin leads. Order some cheap Chinese ones like the links above, but just to get the end clips. Then build your own leads with them using decent cable and decent banana plugs.

I just bought some gear to bounce. Got a tidy looking 50MHz TBS1052B-EDU For under 100 quid. Reckon I can double that just by taking some better photos
tautech can leer at it disapprovingly
Edit: wow even 50MHz analogues go for more than that at the moment https://www.ebay.co.uk/itm/114837779169
... what with all the shit BREXIT is dumping on China-Direct anything now...

You might think it would go that way, but it hasn't. I used to be very cautious with my purchases from China, staying under the, then, VAT de minimus of £15, not to avoid paying VAT but to avoid paying a few quid of VAT and £12 to the Post Office for collecting the VAT from me - something that would turn a £17 purchase into a £30.20 purchase.
The rules post Brexit are that I have to pay VAT on everything, there's no more £15 de minimus but if it's less than £135 + VAT then it's the seller's responsibility to collect VAT and give it to the government. So I no longer have to hedge my bets on whether I'm going to have to pay the "We're the Post Office, suck it up" tax. Under the new regime that putative £17 would become £20.40.

This was nothing to do with leaving the EU, except we couldn't delay the introduction of the new VAT rules for 6 months, like the rest of the EU did for stuff from China & other non-EU countries.

Some inside piccies of the 575
As often the bottom side of the decks are pristine, only the upper parts are filthly because that's where dust and dirt collects, gravity and all that.
WTF - you better mind the notes on the inside of that monster. That nice huge metal panel on the inside that your mind just wants you to attach your scope ground clip to -
CAUTION: DO NOT GROUND THIS CHASSIS

NICE!!! The 575 is one of my favorite instruments. Super versatile.

Yeah and there are info out there to turn it into a tube tester, might be useful to help me restore my 18 (and counting...) Classic Tek scopes....
The 575 is hard to find, but the 570 its tube tester counterpart , it's more like you wonder if it ever existed in real life.... I have never seen one for sale or anywhere other than in the period Tek catalogues...
mmmmmmm... Moldy-Rolla.

Hope you took it to one with a wax stacks specialist. That much tonnage, there have to be a few with actual collector value. Be a shame to see them sold off by the hundredweight...
