Test Equipment Anonymous

Since this will now be our primary hangout I'll continue the Sony/Tek 314 project here.

The procedure for separating the PSU from the chassis is 3 freaking pages long. So I decided that I was not that ambitious and for the time being not to re-cap the PSU but the capacitors are on order. Sometime in future when I'm bored I'll get around to it. In the meantime I checked all the supply voltages via this handy pictorial out of the manual and they are all in spec. The HV measured -1857V vs -1900V which is close enough and didn't fiddle with it.



This is the attenuator section with channel 1 on the left and channel 2 on the right. It uses the same gold leaf contacts found on other Tek scopes. Cleaned each contact with a dab of deoxit followed by a rinse of 100% IPA then blow dry. Any other noisy controls cleaned. The defect the seller noted on channel 1 was simply due to a dirty DC - GND - AC coupling switch.



Left to do is calibration/compensation check. I should have that done later today then it will go for burn-in.

Wow, I've never seen such a switch like that before, one thing is for sure, you can see the state of the contacts clearly, once you have gained access, cleaning should be a breeze.

They look like the finger switches on Tek 400 series scopes. They are notoriously easy to damage, so a delicate touch is needed.

They are exactly the same as those found on 400 series as well as others and yes they are very delicate.

Compensation/calibration check complete. All parameters checked were within spec with just channel 2 needing a very slight tweak of compensation. Display is 1MHz square with the sweep set to X10. Not too shabby for a 10MHz B/W scope.



Outer case re-installed. Jacket included a shoulder strap plus an operators manual.



Set up on bench 2 for burn-in. Unless an issue crops up this project for now is complete.

Looks great, Mike!

The 314 has run many hours of burn-in with no issues. It now joins it's larger cousins on scope art display. A PSU re-cap is still pending but that's sometime in the future.



Other bench happenings. Invasion of the little people. The Type 561B has been returned to the shelf. The CRT that was installed 2 years ago to replace a duff unit is also showing signs of end of life so I want to limit that scope's power up time. A Type 310A with it's fan mount and a Type 321A have taken it's place.

Those three scopes remind me of Bill and Ben the Flowerpot Men and Little Weed.

God knows what they'll get up to while you're away.

4 minutes in my brain turned to mush and I had to stop it.

Note that I added BBCodes for YouTube and Odysee, so you can embed them into your message, if desired. You'll see the buttons for them when editing (odysee and youtube). Hover the mouse cursor over the button to see the syntax. It's just the URL surrounded by the codes, as expected.

I nearly "weed" when I saw that!
Back in the day, I had to sit at a TV transmitter site & "critically monitor" such stuff.

It was perhaps the least annoying of the early British kids shows, being much less so than "Andy Pandy".
Why the Poms thought it was a good idea to have some condescending adult narrating such shows from off camera is beyond me.

When the ABC in Oz was foisting old Brit shows like that on kids, CH9 was producing "The Magic Circle Club", with really well made Puppets & people in elaborate animal costumes.
It was too good to last, though, as it was costly to make, so the "bean counters" killed it!

The ABC, bless their little cotton socks, did pick up the whole crew & make the very similar "Adventure Island", but that in turn, was dropped as "too expensive"----being govt owned, you can imagine how some Senators of the "Jack.S.Phogbound" variety viewed such frivolity.

So it was back to "Bill & Ben" ---"Blobalobb!

Andy Pandy always was dismal beyond words. I suspect that it was the invention of adults that left their children's upbringing to nanny and then boarding schools. (Another product of that was the Minister for the 19th Century, Jacob Rees-Mogg)

Oz gave us that kangaroo (Skippy?) with a young Liza Goddard, and that magic boomerang thing.

The French gave us horses in the Camargue, and the Magic Roundabout (made tolerable by Emma Thompson's father).

Oh how I've missed our threads going completely off the rails.

Welcome home all

Bagpuss (early right to repair!), The Clangers, Mr Benn, Trumpton and Camberwick Green, Will O the Wisp, Why Don't You, Jackanory, The Wombles, to name but a few really good British kids TV shows being made at the same sort of time. Yes there was some dross, but by and large it wasn't too bad.

You're right, I was only thinking last night that since we have what so far is effectively our own little club, just how restrained we have been with OT stuff.

Ok lets fuck that up right now, then, it seems that my solar problem might finally get sorted on November 18th, thats 3 and a half months since I first reported the problem, think of the all the glorious sunshine that has resulted in zero free energy since then. I'm beginning to think the solar panel company is owned by one of the power companies and so had deliberately held back in order to make a bit more insane profit from me

I suppose so, but I thought the thread was more or less finished. MED had done the restoration and presented the scope with two others as a display piece. It's not as bad as his posts on the subject, and replying posts relevant to the Tek 314, being interrupted by talk of long dead kids TV shows.

The Clangers was a quality show. Captain Pugwash and Noggin the Nog were favourites. I always wanted to strangle Noddy.

I always thought the British had higher quality TV shows than the trash on American TV.

How wrong I was.

We do - and don't. The UK definition of "high quality" and "crap" programmes differs from the US definition. Both countries have crap, both countries import the better stuff and ignore the crap. The US has a tendency to import a concept and neuter the features that made it good. "Til Death Us Do Part" -> "All In The Family" is the canonical example.

If you want crap UK programmes search for "Love Thy Neighbour", "Black and White Minstrels", "On The Buses", "The Comedians", "Dixon of Dock Green", "Big Brother" all of which were very popular in their time. But caution: some of those are now NSFW!

I'll wax my skis then and get ready for some serious off-piste.

On the subject of early British Children's Television I am reminded of "Muffin' the Mule", and I have to ask: Is that even legal?

Could be worse:

I remember "Tinky-Winky" being one of the Teletubbies, but not "Twerky-Werky".

Well I think they had a lunchtime session on the hard custard there. All bets are off regarding assigned roles.
