Do you have any test equipment in your lab that uses vacuum tubes?

[mansaxel]

I have a (newly resurrected, see here -- hp) -- 428b, bought as for-parts from the US. With a probe!  I have wanted it since I read about it in (I think) the -- hp -- 410b service manual.

I do not own a 410b; that auction fell through. This time.

I do own a Marconi TF1041B VTVM of 1968 vintage with the whole shebang including a heated probe, also working.

Finally, an Euratele 412 Abgleichsender, also working. My wife found it for me at the large Eskilstuna ham flea market. Yes, I have the best wife in the world.

The Euratele range was, I understand, something of a German Heathkit, "some" assembly required. It does all then-current broadcast bands, and some more on shortwave. Have verified der Abgleichsender on Band II FM (in Sweden, it is allowed to operate a very, very weak Band II FM transmitter for local perusal), and it apparently works across the house, and probably further if you connect a decent antenna to it.

There will undoubtely be more valve equipment coming my way.

Congratulation to that wife 

Don`t forget some of the larger system needs some A for glowing.
When I start here more then 3 from the scopes the fuse of the workroom will stop the job

Are you surprised by that?

I have a three-phase 16A 230/400V supply to the workshop. It is shared with the computers (including a 2KVA UPS with ~270 kilos of battery bank) and the machine workshop, where there are several 3-phase machines like drill press, air compressor, etc. I do not expect fuses blown, but sometimes the RCCB takes a dislike to the devices I connect...

left side from the work table:

Tek 551 (850W)
Tek 555 (1000W)
Tek 555 (1000W) yes, it`s a pir of them
Tek 556 (850W)
Tek 565 (500W)
Tek 549 (600W)
Tek 533A (< 500W)

at the right side from the table ...

Impressive.

L1: 533A+549+565 = 1600W
L2: 555+666 = 1850W
L3: 555+551 = 1850W

L1 is always loaded more than the others, so will get the lowest load. Still, all three phases come in under 10A, with headroom.

Oh, you don't have threephase "Drehstrom" in your workshop? I've lived in apartments with 3x16A main fuse. Sweden, home of ASEA (the A in ABB) and three-phase!

not so easy to calculate that, it was the e left side of the table

Some of mine.

Daaaaang, dude. Hope you have strong floor joists. 

That's a super awesome collection. One day I hope to own one nice example of a Tek vacuum tube scope. Maybe.

[xrunner]

Some of mine.

Wow! 

[Cubdriver]

Schweet bunch of scopes there!!

Wow, are you Paul Carson's neighbor??

Or did you visit Germany and clean out Martin's place?

[VK5RC]

Lovely gear, I can imagine the sound and smell of them being used!

I am having trouble posting but hopefully I can figure it out and put up a few more pictures.

[David Hess]

I have a pair of 500 series Tektronix oscilloscopes, a Tektronix 184 time-mark generator, and a pair of ESI 250DA impedance bridges.

[Larryc001]

A few more.

[Larryc001]

First transistor scope the 321 and 321A.

I should clarify my response and photos. Although all of my many scopes are fully working, I don’t really use them for troubleshooting. They are really a collection. As the topic was more like vacuum tube instruments being actually used, my posts were a bit off topic. I have a 2465A, a 2213, and a 2445 that I use to work on the big scopes. My apologies.

Absolutely nothing wrong with that. Thanks for sharing.

You're wrong, that 2465A, 2213 and 2445 still fall into "vacuum tubes" test equipment as for it's screen. 

Thanks for sharing the collection.

Here is an interesting website from Julian Bunn, a long time electronics enthusiast and Caltech professional. He has a lot of stuff here including the Tektronix portion:

Many tubes here!

I excluded CRT oscilloscopes because EEVBlog does not allow posts that long.

Well, in that case, you need a sanctuary for that kinda post, anytime, you're very welcome at TEA.
