Woot. Might go for that 33120A. No low level out means cocked attenuator relay which is easy to fix.

I was looking at that one and its brother, but figured no way in 'ell either'll go cheap enough I can afford the freight.

*Sigh*

Not sure they'd ship anyway. Haven't dealt with an auction house I'd trust with shipping yet anyway.

What would have been nice is it finishing the weekend before which is the Strawberry Fair in Cambridge. I haven't been to it for a number of years but it was a right laugh back in the early 90s. To quote wikipedia:

"It has been held every year since 1974 except 2010, when it was cancelled due to 'continuing hostility' from drunken attendees and unbridled drug use. After a year's hiatus, the fair continued in a new form, with a perimeter fence erected around the festival and searches to check for excess alcohol, drugs and weapons."

Excess drugs, alcohol and weapons were the only reasons to go dammit!  >:(

Edit: Just had major flashback. I'm not going. Bad idea  :o

Philips Research auction - some interesting stuff up for grabs: https://www2.ppauctions.com/auction.php?id=232

Oh crap. That's close enough that running up there to collect stuff isn't too hard and there's loads of interesting things.

[Shouts aside:] "Honey, you know how you were saying the other day that I don't take you out often enough? D'you fancy a day trip to Cambridge?"
HaHa, thats my line, I agree there is some nice stuff there and it looks like the entire office / lab gear is included in the auction so question is, are they closing down or just moving and can't be arsed to pack and unpack?

You got me wondering... considering how big Philips is globally. A quick Guugle shows only a few hits, mostly from the company itself. One short news article from a year ago tells the story though. It appears that they set up shop with this research lab at the Cambridge Science Park in 2008, and last year decided to pull the plug. Some of the articles I saw showed they mostly worked on high-performance LCD and glasses-free 3D displays.

Quote from:  Cambridge News.co.uk - Nov. 1, 2017

Employees at Cambridge's last remaining outpost of what was once the giant Philips company are set to lose their jobs, workers have told the News .

A member of staff at the Science Park-based electronics firm Philips Research said workers there had been given notice that the facility will close down in March 2018.


Around 40 people are understood to work there.

(SNIP)


Philips has a long association with Cambridge. In the late 1960s, the Dutch firm took over the world-famous Pye group of companies in the city, pioneers of TV and radio sets.

In 1986 Pye Telecom, the radio communications division, was renamed Philips Radio Communications Systems and grew into a £200 million turnover international group of companies.

W G Pye, founded in Victorian times, became Philips Scientific in 1988.

Two Cambridgeshire-based descendants of Pye, Sepura PLC and Team Simoco Group, are still leading companies in radio communications.

[Full story here]

So lots of history there but nope; not coming back.  :(

On the subject of Philips, I think we should roll back technology to 1960-1980. Far more interesting and I could have landed a job there instead and done some analogue stuff rather than ending up in software.

On a side note, I've been playing with a re-thinking of the Tektronix 130 LC meter with some slightly more modern parts? Why, for the hell of it! Plus I'm getting bored of sitting in front of Kicad. I'm much more happy with a pencil, some paper, a calculator and a soldering iron in hand.

The 130 is a neat little tube based device which uses a pair of oscillators running at around 140KHz. You null the fixture by zero beating them with a variable capacitor. These drive two inputs on a mixer, an LPF and then a schmitt trigger and then a pulse integrator. This ultimately gives a very linear reading of the difference frequency between the oscillators.  You connect the DUT, a low value L or C to one of them and the second oscillator slows down. The difference is recorded as a voltage and deflects a panel meter.

Theres a rather nice (but large) HP LCR meter in the Philips auction, in fact the same type as in that rifa video of Simon's that you posted earlier.

Not sure they'll ever be big enough; they're actual Christmas trees. Pines and firs intended to be planted whole as landscaping. I suspect they may be some midget variety, as they seemed to spring up to 6-10 feet in no time, then lingered thereabouts for years.

Oh yeah... it's probably as old as blinkenlighten. My other favorite version is the Management Problem Solving Flowchart; not so much because it's funny, but because literal, direct application at work as insight into the source of all the "shit that rolls downhill" has saved my ass more than a few times.

Woot. Might go for that 33120A. No low level out means cocked attenuator relay which is easy to fix.

I was looking at that one and its brother, but figured no way in 'ell either'll go cheap enough I can afford the freight.

*Sigh*

Oh, wow man... We have a similar thing here in Poteet, TX; the Poteet Strawberry Festival every April. And EXACTLY the same hazards! One of the many reasons I'm looking to get the flurp outta Texas!

Crazy that we have the same small town right around the corner here on the other side of the pond!

And not the fun kind of crazy, I promise you.

Wasn't Pye a Test and Measurement manufacturer in it's own right? I vaguely remember trying to fix a HV voltmeter with light spot indicator. But I'm not totally sure about the name.

Yeah, most auction houses in the US that I've seen don't ship. They'll have a list of couriers that you can hire or you can send your own service/schlepper out to pick up. So far, I've only bought from local auctions. Much simpler and I know it'll make it home safely. If it doesn't, then I guess I'll need a more crafty flowchart. :-DD

My guess would be that was produced by Pye Telecommunications in the 40s and later; evidently they enjoyed some significant popularity as mobile radio providers for police and military during and after the war. They even made some of the early RADAR receivers used in wartime according to the wiki.

Yes that's exactly what Pye used to do besides a few domestic radios and TVs. I lived in Haverhill for a time many years ago and they had a factory there solely making the Police radios. My ex worked there till they closed it down and I believe they relocated to Cambridge.

This morning I got a SMS message informing me that Royal Mail will be delivering a parcel to me today from 4PX, does anyone know what 4PX is?

The only 2 items I'm waiting for is a package from China and its way too early for that, and the other is my meter from RS but their website has been updated and unless they've changed name, it won't be from them either?? :-//
