Looking at the service manual, I was able to find the replacement parts for the front and rear bezels in ebay, but those are for the HP3577B. Please, can someone confirm that these are equivalent? In the service manual these parts appear with different codes for the 3577A (front: 5020-8807, rear: 5020-8808) and 3577B (front: 5021-8407, rear: 5021-5808)

If the part number is different they would probably not fit on your 3577A. Normally if the part number is different, the part itself is also different.

Also, does somebody know if Keysight is still selling parts for this instruments? it seems that this frame/chassis is used in many other HP/Agilent instruments. I would prefer to buy it from them than from ebay.

Keysight is selling parts but the HP3577A is really old. I would be surprise if they still have parts for this instrument. You could contact them but ebay is probably your best bet.

I have to disagree, the later frames will almost certainly fit. They might have minor differences, the worst likely to be metric threads rather than imperial (you could check the prt number of the fasteners for the A and B models). Many keysight parts have later numbers but are still usable.
Keysight still list the later frame

About $90

Well it's a gamble. Might fit but it's not exactly the same part.

Personally, since it's probably aluminum, I would simply try to use those brazing rods to repair the frame.

The frames are common across many instruments. The part number is likely for a minor production change or maybe colour.

Hey, thanks to all who replied for your suggestions and nice ideas.

For now I will try to get the front panel bezel and the side handles from Keysight. It seems that modern 5U front handles are compatible (model 1CN005A), so I will try to order both parts from Keysight directly. I may try to repair the broken frame with one of these brazing rods, after replacing it with the new one, for the sake of science. I will post how it goes, but it will take some time, since I will have a move soon.

Hey all, am I crazy to consider spending over £4,000 on a 53230A -KEYSIGHT TECHNOLOGIES - Frequency Counter, 10Hz to 350MHz, 12 Digits, 14 mVrms, 53200A Series (https://export.farnell.com/keysight-technologies/53230a/universal-counter-350mhz-12digit/dp/1843579)??

It's going to be the first Frequency counter on my bench, and I'm looking at getting a few 10Mhz references... consider this my start into high-accuracy time-keeping fun. It's just downhill from here right?

Probably 
What are you using it for?
Is it paying work or hobby?
It's a nice counter and looking at your declared location I'm guessing there is not much choice in used. It is however a big chunk of change for one instrument. You should be able to get a used 5370B or SRS counter for a lot less. A lot of the real Time Nuts are not even using traditional counters these days. A microchip PIC based time interval counter costing a few dollars will give you lots of good data to play with if statistics are your "thing". Google PICTIC

Put on aluminium knobs. I now declare it audiophile grade and shall raise the price trifold.

[med6753]

Anyway, without further delay. Here's what is sitting in the back of the CR-V. A Type 547. And the reason the panel it is sitting on appears slightly elevated is because the full size round rubber thing with the spike in it is under there. Doesn't fit properly because it only has enough room for the temporary round rubber thing which is currently mounted on right rear. New full size rubber round thing is on order and will be here Monday.

More info on the 547 later. Also attached is the original CL ad.

All this talk of tyres is tyring. 

I always have to laugh when Americans try to "correct" English speakers on their spelling! Here's one for you:

On labour day I went over to my humourous neighbour to borrow his coloured tyre guage.

I never claimed I could spell, but I knew there was a "u" in there somewhere.

Nice score, Mike!  Hope your back gets to feeling better so you can get it inside.

This one's just for you, BU508A. 

More cheap "Dupont" connectors... This time, since the wire is only 26 gauge, I used the smaller crimp slot. Excellent crimp, and both terminals fit in the shell perfectly without any post-op fuckery required. I now have power for my new redundant CPU temp gauge.    That doesn't make the crimps any less cheap crap, of course.

This chip shortage sucks. At this point not just parts, but entire product categories are out of stock. Can't design around that.

[mnementh]

I was looking today at this beauty:   

So in order to get closure i dug deep into my pockets ad bought the 250 watt model  here:   https://www.aliexpress.com/item/4000512825009.html

Bwahahahaha!

Good choice. I have two; one for quick & lazy power, and another set up as a cheap & cheerful ATX load tester.

Hmmmmm

@Specmaster:
You mean, the tyre of med6753 is going to be retyred, then?

How did BU508A feel after med's CR-V drove over him?

Tyred and exhausted.

[mnementh]

I just realized with all this agitatin', I forgot to congratulate you on your new enheavyment, med. Excellent find.



Eat it in good health!

Mini rant: Kubernetes is Pandora’s box incarnate. No one knows entirely how it works. No one knows entirely what it does. But the outcome is nearly always mayhem and chaos. Much like “The Cube”, it is written by lots of people who independently concentrate on their little bits of the machine unaware of each other and the sum of the parts resulting in the destructive potential for the cumulative pile of mistakes in each part. From synchronising state across several partitions, through Rube Goldberg chains of events, struggling through eventual inconsistency and landing on mutant vocabulary they have succeeded only in removing understanding and determinism from computing. When all hell breaks loose you cannot reason about fixing it because of the inane complexity because you can’t communicate the problem nor rationalise it due to the non determinism.

At this point I am going to sit back, buy test gear to play with and watch it all fucking burn and hope I get paid to pretend I give a shit.

If this is entire thing means nothing to you then you are lucky bastards.

And med, nice score. Even if it cost you a tyre

[Cerebus]

Nice score, Mike!  Hope your back gets to feeling better so you can get it inside.

He should get himself a hand-truck, with some of those little round rubber things on it, perhaps even of the stair-climbing variety. Or perhaps it's better to just go straight to the Zimmer frame.

I've realised I never oughta go close it. Sooner or later a multiuser operating system with several processes coöperating in a common namespace will be the thing again. Or I'll run FreeBSD jails if I have to. On top of bhyve.

Karma is good to me after that rant. I just bought a 3478A to match the 5384A
