I got one of those little scopes, ideal for that type of thing, will work of a 9v and although have a low bandwidth are ideal use on low stuff like cars and audio where often you just need to confirm if a signal is present or not.
The DSO138 was a cheap purchase which would give me some SMD soldering experience. A little DSO was a project that might be of some use - more than a practice board to flash some LEDs. It's not the most friendly to use, but it does have its moments.
$487 USD to have an alternator drive belt replaced? Other than that I'm speechless.
Yeah one of my current colleagues at the moment has the same vehicle. I think they had to take the engine out to fix something trivial recently on it. Mine is apparently the same. Similar to a Tek 465 multiplier
Hope your ankle gets better soon
Think we should all buy a Land Rover defender. The broken bits fall off when they're ready to be replaced
Was considering buying one again recently.
I'm a big fan of German engineering. They come up with some innovative, clever, and technologically leading designs. But there are two things they seem to forget. One.....serviceability. Example: Certain model Audi's where you have to disassemble the ENTIRE front end of the car to do the mandatory replacement of the timing belt. And my oldest son is the collision manager for a local BMW dealership. Some of things they have to do to fix BMW's just leaves me shaking my head. Second.....why are some designs so needlessly complex when a simpler solution will work just fine? Called the KISS principle.....Keep It Simple Stupid.

I think being bitten by it is rite of passage
The thing that always gets me is the bits of kit which specifically have an X2 capacitor across the inlet before the switch. When I'm unplugging shit on the bench and moving things around I'll occasionally stick my fingers across the plug pins by accident and that little bastard will empty into me. Depending on where it was on the AC cycle when you pulled the plug this can be somewhere between "hmm" to "holy fuckadoodle you little wanker". Either way the plug gets dropped which is hazardous with our monstrous things. I'm waiting until I drop one on a toe or something.
You can get trainers with steel toecaps for £25. They also protect against teenagers trying to influence you by treading on your toes: simply smile beatifically, and say "my turn now".
That... that is the embodiment of another of grand-dad's favorite sayings: "Old age and treachery will win out over youth & exuberance EVERY TIME."

Best bite other than a 5KV 3ms electric fence zap was when I was just 13, building a valve PSU and got zapped from the 700V 100mA on the plates of the rectifier tube. OUCH !
When she was in an ornery phase, I used an electric fence to teach my pre-teen daughter not to fiddle with electrickery. Got her to make a fist and lightly touch the fence with her knuckles - and why doing it that way ensured her muscles wouldn't be locked with her still gripping the cable. Yes, an exaggeration, but all in a good cause.
When we are going to assemble the high voltage power supply for the anode of the GU81-M, we got a security advice from our Prof.: "Be careful, when you are handling with that capacitor. The energy in it can kill a cow instantly." And that was all he wrote.
Btw, the capacitor was one of those paraffine filled ones with 3.5kV max voltage and a capacity of about 4.7µF. We were running the GU81-M with 2500V.
This is a similiar looking example: We had a lot of fun.

Holy crap you guys have been getting some good zaps and some of the descriptions of them have had me chortling like a good un here, especially bd139's "holy fuckadoodle you little wanker" I can just picture him muttering those words when he stuffs his porkers in the sockets. Would have thought by now, you'd learnt the lesson not to fucking do that cos it bitesI'm a slow learner

In the meantime I suppose you could try probing with the 12AX7 out of circuit; see if the 60hz noise you're "seeing everywhere" goes away.

Obviously, I need start catching up fully on the thread BEFORE I post.
