The big reveal. The NiCad packs are intact and not leaking.  But they are apparently deader than dead. I tried applying mains and don't even get a power light. The batteries apparently are part of the overall PSU and if one of the packs goes open you gots no power. Another good thing is that I don't think anyone has been in here since it left the factory. So no Gorilla activity. But not so the probes. They are missing and instead are BNC males. But that's no big deal really, I'll figure something out.

I understand you can remove the batteries and install jumpers to get the PSU to come up. Will investigate that tomorrow.

I hope for your sake the PSU is less quirky than the 1502. With that you need working batteries; there are "battery fakers", but in my experience they aren't reliable.

ISTR something about the 212's probes being special, but that might be a faulty neuron firing. Naturally you will have a look at https://w140.com/tekwiki/wiki/212 and the TekScopes archives

First, Baby Tek 212.

How cute. But the blue plastic housing looks like something made in the Soviet Union, colour, burrs and all.

500 USD for an empty box with 6 binding posts

[Saskia]

that's cheap. Believe it or not, they want 500k or so for an empty missile silo ... What can you possibly do with it when the ICBM is missing ??!!!!

[bd139]

Install a new one?

Some fool will buy it. But it won't be this fool.

Sold my pussycat, the one with the 416 horses ...  Proceeds will go towards a house.

All kinds of mayhem and no one would be none the wiser. Explosions, gunshots, etc. Right up your alley.

Hey they have "Make an offer" available.

hmm ...

for those who don't know, this was my certification rocket that I had to build to prove to the authorities that I could actually do this.
On this flight it reached 148 m/s, 808m altitude and had a take off weight of approximately 4.5 kg

Major TEA today.
Picked up 2 HP VNA, 2 S parameter test sets, HP 9122 FDD, Prema 6030 61/2 digit DMM with math, Lowe HF225 receiver, Philips PM5110 AF osc, 8750A storage normaliser, 11850C power splitter, Suhner crimp tool, various coax adaptor and cal bits.
All in excellent condition with all the proper interconnection leads, original manuals and even the smith chart overlay acetates for the VNA.

[Saskia]

congratulations "!

Agree. The mechanics of a NOTAR is not simpler than a tail rotor. I doubt its more reliable as well.

[AVGresponding]

The NOTAR design is not simpler than a conventional tail rotor and does not use the engine exhaust. This is a common misconception.  It uses a fan driven from the engine and as engine RPM is basically fixed in a helo it has to be variable pitch.
Most of the anti-torque  comes from the side of the tail boom. There is a slot along the boom that blows air across it creating sideways "lift". The rotating nozzle at the end is fine tuning. 
The only real advantage over a fennestron is low noise.

ehhh... that's a bit shit then.

I thought the battery packs were not leaking in the 214 at work, but on removing the tape & end covers, it revealed the early stages of leakage, a few more years & it would have been a write off, you have been warned.

wet his balls, cream with soap and attach to a 24V truck battery.

I don't know what you're making a fuss about you're the one that likes nekkid electronics!

Take it off! Take it all off!   

LOL! 

And it's nekkid again, only this time it's going back together.

May his punk turn to steam.

need more voltage to do that ... maybe an 800V electric car battery would do that ...

Thanks for the warning but I figure by tomorrow afternoon those NiCads will be history.

Give each cell a few seconds at 24V and see if they polarize and hold a small charge.

What makes you think it was dropped? I see no evidence of that.
