With the latest shelf addition here is an update of the entire man cave....or what I call "The SWMBO Interference Free Zone"  :-DD

Far left. The Video and static displays.


Continuing to the right. Audio system plus new shelf connecting it to Bench A.

Edit....also have another small TEA related woodworking project that I should have done in a few days.

Well that sucks!  :--

Not all roses. The vertical channel A fine is locked to the main attenuator. Looks like there was a botched repair done. Someone has properly fucked it.
When you say locked, do you mean that the fine control can't be used without the main control also turning? If so it probbibly has had a clout on the knob, bending the shaft. Been there with my 4 tracer and it sucks, but it might be usable if you hold the main and rotate the fine?

That was probably what happened initially. Basically the friction between the fine control and the main attenuator means the fine control turns when the attenuator control turns. It is not adjustable as I popped the knob cap off expecting to see the usual nut to undo but what I found was a glued in DIY plastic collet on the main shaft meaning the knob is on there forever. On channel A, the knob cap wont even come off because it's glued on.  :--

Seller has suggested he refunds the repair cost but without another scope with known good attenuators I think that's impossible.

Edit: happy ending. Seller has refunded the entire amount and said keep it. I am impressed. Apparently it was bought and stored and not tested so fair game it was handled quickly and professionally. I'll store it for now and keep an eye out for another one.

Edit 2: ok have cut one of the knobs off. They are indeed glued on and the glue seeped into the shaft on the A chan.  :scared:

Happened to me twice on ebay. Got a Prema 5017 for free like that. Just needed couples of new Caps  ;D

@BU508A: thanks for posting that. Beautiful piece of equipment! I should probably look out for a commercial VTVM here instead. They are usually built by more competent people  :-DD . Marconi did some really nice ones that turn up here occasionally. Also they're weird because the meter is upside down.

Agreed! I was thinking the build quality on that unit looks more like medical or mil-spec hardware. VERY well thought out. I also like the fact it has the AC cord exiting the front; this is a feature usually found on gear intended to be used while kept inside an accessory storage case, or for small workbenches where test equipment is kept in a locker (Naval comms, etc) and only brought to the bench during actual use.

A delightfully well-preserved specimen... no idea WHY a postal service would need such hardened and high-quality gear though...  :wtf:?!?

Mayhaps something to do with the fact that back in the day, ex-military often wound up working at the Post Office due to the bureaucratic and regimented nature of the work. Gotta keep it all ship-shape!!!

Oh fudge... I just realized. I've inadvertently given you a new quest... to find the storage cases doubtlessly made for these meters.  :palm:

Thank you for sharing, Mounty!

Carry on!

(Attachment Link)    THE BITCH LIVES.
 |O   While researching possible compatibility issues with my particular combination of CPU/RAM/MB (Even though my exact RAM is listed on the MB's QVL), I was led back to the MB support page where I discovered a new BIOS released JUST YESTERDAY. In desperation, I Q-FLASHED it again... and it booted to BIOS. The aggravating part is it still refuses to boot with XMP enabled; so RAM just operates at slowest JEDEC speed of 2667.  |O I suspect the main difference is just that prior BIOS versions defaulted to XMP ENABLED, while this version doesn't.  :palm:

I think I'm going to accept this small victory and go to bed.

mnem
Sufficient unto the day is the evil thereof.

So... after researching the issue, it appears the main problem (aside from dumb fuckups in the BIOS like leaving XMP turned on) is that to get the advertised speeds with RYZEN 3xxxX processors, you have to do some matched OCing of the CPU along with the "MFR-Supported" OCing of the RAM provided by the RAM's XMP profile. Problem is, those XMP profiles are a Intel thing, and these processors are so new, they haven't got the equivalent XMP profiling done yet for AMD CPUs so the memory timing will sync.  :palm:

So, in short... my RAM is new enough and high-performance enough that the 3700X can't keep up stock out of the box; I have to manually OC it to match the RAM. Which is really hard to do when the effing thing won't even POST because they left XMP on as a default. |O

Moving forward...

After having a chance to sleep on it... and knowing how I tend to obsess (*looks at self indignantly* "MOI?!?") over things... I've realized that even though I have the problem licked (I KNEW it was something STUPID) with this MB, after doing the "deep dive" into the differences between the Aorus Elite and the Aorus Pro I still feel like I'm "settling" with the Aorus Elite MB.   :palm:

I'm going to go get the Pro just so it will stop niggling at me.   |O

All is well that ends well, find another and you have a parts mule already. They do sadly tend to come along infrequently though but as long you can patient I'm certain you'll have a scope to be proud of at the end. [emoji4]

Looking good !

Got 3 benchs myself and for some reason they are always full when i'm working on something. Got to discipline myself to clean everything at the end of a project. Maybe I should build another one  :)

At the moment I'm in between projects and I haven't made up my mind as to what project is next. Also, since it is my living room I do tend to want to keep it somewhat neat and tidy.

Thank you mnem for your kind words.  :)

The thing with the German Post is: back in the 70's they were also a phone company,
today known as the magenta coloured German Telekom. That's why you can find on top
of the meter this logo (right next the "URU"):



And this is a better visible version of this logo:

Hei bd,

since you are having so much fun with your Heathkit VTVM
I thought, I'll show you some photos of one of my four (don't ask   ::) ) VTVM.   ;D

They are from Rohde & Schwarz, mostly made for the German Post
back in the 60's and 70's. They are called URU 1080BN and are
heavy and sturdy as hell. The case is made of 1mm steel.


Cool! Added it to the POI.
I TEA.

Re 'Post' running telephone - that also happened in Australia - it was called the Post Master General or PMG - they also did most of the moderate level electronics training as well - a lot of my Ham club are ex PMG employees. I have several bits of gear labeled PMG.
PMG got privatised and is now called Telstra.
Whoah! Watch where that landed we might need it later.

The latest TEA related woodworking project is done and installed a day early. Pix 1 shows an under utilized space between the audio system and bench A. Pix 2 shows the solution. This was actually inspired by the lady cop. She sarcastically remarked one day “I'm surprised you don't kick out that plant and use that space”.  ::) Well my dear, your wish is my command.  :-+ Space now better utilized. Now I'm sure when she sees it I'm going to get a massive eye roll and a “you ain't right”. To which I am going to reply: “Well if you hadn't opened your mouth I probably wouldn't have thought of it”.  :P Now for my young friends, this is how you catch fleas because you will be in the dog house.  :palm: You never, EVER, call out a woman on something she said.  :scared: Not a healthy thing to do. But I'm too old and stupid to care. She'll get over it.  ;D

And for you plant lovers. Don't not fret. The plant is fine. Moved to another location which actually provides it with better sunshine.



Can't argue with results that are both aesthetically pleasing and space efficient. :-+
I TEA.

You should see it on my 46" LED TV that I am currently using for a monitor.  Looks almost life size. :-DD

Awesome job on the bench, med.  Bench envy now.  I can build for function but not really for aesthetics.

That which doesn't kill you still requires a co-pay.
