Fluke 540B Thermal Transfer Standard w/ A54-2 Voltage Plug-in Unit (1): appears to work exactly as it should, battery is being charged 'time meow'.

*Once I get the bigger standards back up on the bench (upstairs), I'll take and post pics of these units doing WORK!  ^-^

I may be interested in a "HP 3408B with 3482A DC range unit" if you still have one.
But first, two questions.. How much do you want and will you ship to Japan? :)

(It would look nice sitting there on my bench with the 5340A complete with nixies that I am currently restoring.)

Any circuit design must contain at least one part which is obsolete, two parts which are unobtainable, and three parts which are still under development.

For sure! I have 4 of them that need some work. Yes that’s right FIVE total. Four needs some love but one is stacked, minus current shunts card, but the case it is in a bit banged up. Make me an offer I can’t refuse and I’ll send them FOUR of them your way, if you'd like of course. (One has been set aside for another forum friend).

***edit: another forum member just requested the working unit, so I will have four that I will post shortly so so can see the various states and functionality.

TEN-TEC Titan 425A Linear Amplifier with owners manual: unable to test because I am missing the power cord,

I have already planned a trip back to get the important items like this so fingers-crossed, its laying around the shop!

But this doesn't have a spec of dust on it, and I didnt clean it, so I have a feeling ti was in constant use on the bench somewhere near the radio's.

The other four of the HP3480B's with 3482A DC Range:  they all power on, but need some work

Testing, photographing, and uploading them one at a time takes a lot of time, so I will not go through them individually unless I "have" to (on eBay).

***I also have a nice lot of tubes for these that will got with the lot if you take all four.***

I can imagine.  This would be a challenge in itself, without the additional forum efforts.

I just had to share the laugh with you.

Fluke 382A_DC_Voltage_&_Current Standard: pictures are worth 1000 words... 1fV-50V's

Sorry to be "that guy" but do you mean it responds on the 10uV range? I think with six dials and a 5V range the best you get is there. Or are you looking at AC ripple noise on the output?

Hmmmm, it does do 5mA full scale, so it does do 10nA resolution, which is pretty darn impressive.

Its hard to find recennt references for the Boonton gear (its has a sister power meter that will go with it) so I just left it up for offer.

Same with the Fluke 382A( though with this one, I have seen what the last few on eBay have sold for, working as should and within specs).

****Basically, everything I list and sell needs to add up to $8800, to keep my word.****

**why i didnt just put the 731 right over the 3456s display for these pics, D'oh!***

$300, price references here:   

https://www.ebay.com/sch/i.html?_from=R40&_nkw=fluke+731B&_sacat=0&rt=nc&LH_Sold=1&LH_Complete=1

***just checking calibration of the probe here @ 1uW***

Just an FYI here - Minimum frequency for the 8484A is 10MHz and the Boonton is a 1MHz output so that will impact the reading. In the 8480 series of sensors you want an 8482 as it covers 1MHz. I'm not sure how far out the 8484A will be as while I have 8484A's I also have 8482A's for below 10MHz.

Unit looks in good condition though - Please PM me if you can't come to agreement with 4thDoctor on a price for the unit as I think it might be useful for my Dad in his wireless shack (I also have a 432A-H76 so I can set the 50MHz output on the power meters directly).

Good luck with the rest of the gear.

Right on man, & thanks for the heads up. I scarcely have the time to read all the book for this stuff, so these kind of pointers are HUGELY helpful. I am trying my best to advertise everything correctly. The REF sticker on the back only specifies errors down to .1000GHz, so yeah I am WAY off. Hum...let me see what else I have in the GHz range to do this correctly.

I did get an offer out of Hong Kong, but no reply yet, & I have no idea if its real (user with just 8 posts here, 6 months in). If it falls through or not; I am inclined to take "1st cash" so if you want it, let me know. I also have two Boonton Sensors, 4200-5E & 4210-4E, but don't have the correct cables/ adapters to test them.
(however, I am planning a trip back next week to pick up these little odds and ends so hopefully I can complete these sets.)

Thanks again brotha!

I found an HP8672A, 2-18GHz, but have no idea how to use it (its a HEAVY beast), watching this now:  http://www.youtube.com/watch?v=bFWzrNIDwW0, hopefully 24 mins from now, I'll understand it a bit better and I am not even sure if it works, but it does power on. If you have any ideas, please let me know. If you PM ill send you my email if you are willing to help me through it so I can test this stuff correctly before you (may) buy it.

Happy to help. I still have that 8672A from the video (I replaced it with an 8673B). They're good units and fairly straight forward once you get the understanding of the user interface.

Will PM you.
