It is quite entertaining watching my daughter respond when letting agents and landlords "try it on" assuming she is merely a "little lady". They retire bruised, and don't mess with her again.

Hell, just put RGB LEDs next to the ports...

Doesn’t work like that. You can buy it not. If you buy it you have to drink whatever excrement the manufacturer served.

As for RGB LEDs that’s fine until you have the probe tips ringed and need an LED at that end too…

Actually once you've got enough probes on the table it would be quite useful to have an LED near the probe tip that you could light up to find out which probe's where.

Yep, probe ID might be needed with our new 8ch monster especially when these can be daisy chained together for up to 512 channels !  :scared:

Custom trace colors will be no problem though as this feature is already present in a few Siglent models although another concern is does the palette have 512 colors to have one for every channel trace ?  :-//

A quick play with the new flagship just to check it was all working like lesser models do.
512 visually different traces will prove to be a challenge though.

Oh no... just looked at the specs of these two 2N2904A I have here.... turns out they are simply a 2N2905A but with ... 2.5 times less gain !  :scared:

IOW, it's just a VERY shitty 2N2905, so there is absolutely, abbbbbbsolutely ZERO reason not to scrap them.
Except... look at them, how cute they are.. aren't they... nice TO39 metal can with gold plated leads AND the bottom of the can is plated as well ! I just can't resist... I just don't have the heart to scrap such beauties... I am sorry.. I just can't !  :palm:   I know, I know... I am weak... very very very weak..... pfff.....  :-//

Where do you even find lots like that ?!  :-//
Specialized websites clearing stuff out ?!
I wish I could find stuff like that !

I wish it was that easy. This is a dying ex EE relative. The guy has lots of ancient stuff but it has been stored in a damp garage with damaged roof for the best part of 25 years so it's nearly all a write off and will be loaded into a skip. The tubes and some of the components were stored in the (heated) outbuilding fortunately because the garage was full. Going to be a shitty long weekend dealing with it so I'm not exactly thrilled at the idea.

I've been told I can do what I want with it so I'm going to lift the high value tubes and sell individually and the rest go in lots on ebay.

I'll enumerate and heater test (I'm not buying a tube tester) all of them so if anyone needs any for genuine purposes i.e. loading up test gear and not building guitar amps I'll distribute them for postage cost accordingly.

Fuck....no envy for you on this one only the sadness I know that will haunt you for every minute of it.  :(
Though he might turn in his grave at you parting out all the tubes he should also smile that you're gunna cash in on all the hollow glass worshippers.  >:D

Oh no he's a complete fucking asshole of a human and always has been. I'm just doing it for his daughter (my father's third ex-wife).

Oh he's also a ham. 80m and 2m health complaint, racist, sexist sorta guy. Real nice company. Fortunately his antenna collapsed in the storms about 3 years ago  :-DD

If and when you get to that ugly task there are definitely some vacuum tube types that I would like to have for spares and I'll gladly pay postage from the UK. When I get a chance I'll prepare my wish list.

Was wondering what this scope daisy chaining was all about, so had a quick look at your link... OK I understand better now, makes more sense... it's not bench scopes being linked together, just front ends  reporting to a computer for display there. So just one screen, the computer.

Well I think colours only makes sense/work if there are only a handful / small number of them, so that the brain can easily/quickly, and reliably tell them apart. To me even 8 is starting to get a bit messy, so 512 oh my god... simply useless.

So I guess if I were writing the S/W of this PC based scope, I would combine colours and numbers, or labels. Use a handful of colours to create groups of traces related to each other, that make sense to the user, whatever that maybe. Then for each colour, just number the traces, and if the user wants to bother/take the time, let him replace the number by a user created label that makes it more explicit.

Something like that.... but it's never gonna be easy for the user no matter what. 512 is just ... hopefully just for marketing / bragging / dick contest, but no real world user will actually ever want to use that many channels at the same time  :scared:
