Is this Anritsu S331A worth bidding for, the user manual has a nice cable velocity chart ?

I don't think it's worth that.

Sometimes an electronic load is too sophisticated ...

... for me.   

Luckily I'm kind of TEAed. So my addicted brain came up with a perfect solution: Collecting the real thing:

10 Ohm 8 A and 100 Ohm 2.5 A.
Remember me of the school time in the 70s.
Now, when anybody dares to ask about Ohms law, I can easily evoke a PTSD by clunking these guys on the table.   

After some mechanical readjustment and a careful 600's sanding of the winding's contact area and they are going smoothly again.

"vermutlich verbastelt", I wouldn't touch it.

[BU508A]

Today the package from BU508A arrived, seems like some adventureous components also managed to sneak in there
Thats all, thanks & have a nice day

My pleasure! 

Thanks for the feedback.

I just a missing screw, gone since they replaced the leaky Akku, but no problem, I have many screws

Ah yes those remind me of school too. The smell is unbeatable when they get a bit too warm. They made us put together measurement bridges in physics A level. I think I was the only one who gave a crap about that lab

We only had the open frame ones though

Think I need to find manual to progress this further, radiomuseum have the circuit diagram but it will take two months to download the set as I'm not a member and don't want to join.

KO4BB offers the service manual for the 5245L for download

Sorry, you are searching for the Philips SM... 

Maybe I should have been clearer, the 5245L (which is working fine) was only used for checking the difference in readings on the Philips PM6645 and to check the oven was still running after my mishap. 

I now have three pdf files for the PM6645 covered in RM watermarks (& name & email) covering part of the input board (or one page of the original manual), yes it's actually going to take a long time to download the rest, I think they are logging IP address to prevent using another email, browser or another device on the same network. 

Oh, and I have several dead tree editions of the 5245L manual, last one was only 99p as no one else bid, local too so no postage to pay.

Yes nice smell of burning dust if they haven't been used for a while, we used them a lot at work for load testing DC-DC converters and also as a load representing a motor field winding for various regulators, nice sound from the changing pulse width too.

I have this nice vintage 6.7Ω one rated at 8.5A in war finish, acquired for a couple of £ a few years ago. There is a non-linear one here somewhere too, that is in very poor condition.




Almost perfect for checking the Sorensen (aka xantrex) power supply I have, which reminds me I never uploaded the teardown pics for that.

That's like "Lets make the heads of BSW screws and nuts one size smaller to save material" and "Let's paint steam engines all black instead of racing green", right? Austerity measures.

The Germans could, too. The Wikipedia article on austerity measures in locomotive building is instructive

[bd139]

Interesting. That'll be my Wikipedia rabbit hole for the evening. Thanks for that

Yes that sort of thing and reducing the amount of certain metals that were scarce at the time, no fancy paper or embossing for books & paperwork for equipment made then.

Some more variable resistances and the non-linear one made for controlling dynamo field current.



Some of those have since been stripped, the rust cleaned off & reassembled.

In the UK "War Finish" is normally found on castings. Basically minimal clean-up of flash etc, no filling before painting  and defects that don't affect function allowed. The marking was so that items below the makers usual quality standards were not rejected.

I HAVE THA POWAAAAHHHH!!!

$40 worth of old laptop batteries to bust up for cells... These are all 6-8 years old, and some even show live voltage output, so haven't discharged enuf to trip ODP. I hope for enuf to make at least one good e-Bike pack.

Now to get crackin'... packs.

Similar resistors "Rheostats" where commonly used for stage light dimming before the advent of semicondutor dimmers. It got pretty hot up on the lighting control deck with banks of those. Would not pass modern safety tests either.
Just reminded me of one production where there was a scene of dancing skeletons comprising a group of girls in black body suits fluorescent paint and black lights. We told the girls before the dress rehearsal to wear black underwear. Needless to say the didn't listen and when the black lights came on the skeletons were wearing bras and panties 

[VK5RC]

Finished adjusting the Cesium standard, cleaned it up. Now it locks without manual adjustments. Turn it on and it locks.

Me happy.

Me envious 😁
Enjoy 👍

At least some decency on the side of the deceased! Must've been British!

[Neomys Sapiens]

As I had a lot of serial interface troubles recently with a GPS receiver at work and I could not locate the copy of the ingenious 'Serialtest' SW which I once had, I could not pass on this Siemens serial comms test set for 10.50€. Supposedly working, incl. accessories & manual.

Also the second specimen of the original Metrawatt thermocouple probes intended for use with the Unigor6e multimeter. So I have immersion and surface probe now. Yay!

I was just going to say that there were similar resistors used as stage dimmers, I remember seeing them at various theatres back in the day.

I also joined that website / forum but because of all their rules etc, I never renewed the membership, infact I think I was banned from it because  I never lists of my radios etc and did any write-ups on them, very unfriendly mob, there is zero comparison between them and this forum, we are very take us as you find us, and friendly, they are all sort of stiff backed upright and proper like and extremely klickly IMV.

I never joined because their requirements for personal information are out of line, especially these days.

So, instead of just swinging them around, they want photos, dimensions, statistics and history?

Sick sick sick individual.

If ever the world collapses and all we're left with is line printers you'll be the king of humanity though 

          Bwahahaha!

I'll make sure to be the bastard with all the working ribbons then. 

Dot Matrix printers?

Ah, the screech of a DecWriter as it prints your program's listing.

And kids nowadays moan about fans whining.

I loved it when somebody else was printing reams of crap for some private project or other, & I was trying to print some work stuff that needed to be done "now".

I would make sure all was clear, ask the thing to "print".

After waiting for a short time,  no page printer indication on the screen, but I could hear "snork!, snork!, snork! coming from the printer room.
Sure enough, the guy had gazumphed me again, & my stuff had defauited to the dot matrix printer ----aaaarrrrgggghhhh!
