As a matter of bringing some perspective to this discussion, I reached out to hkz on Mastodon. Here's the statement I received:

If you can stretch the top end of the budget by $4, you can get a Rigol DHO802: https://www.rigolna.com/products/rigol-digital-oscilloscopes/dho800/ Like with the previous DS1054z and similar models, it looks like you can flash modified firmware to unlock 100MHz rates...

Looking at it from another angle: You don't have to use that specific standoff for the grounding lead, any of them will work.

I've been perfectly happy with my Rigol DS1054Z, I bought a refurb unit from them probably 5 years ago and it even came pre-hacked to 100MHz!

P1 on the analog board is Molex part number 15311046, and the shell for the CRT cable side is 19091049. Both are available from Mouser/Digi-Key if you'd rather order them that way.

This is what I did. I used 3M VHB tape to stick the bare extender slot PCB to the bracket. I've attached the STL of a bracket I designed, but that reminds me I need to upload it to Printables too...

I'd give FWB CD-ROM Toolkit a shot instead of the patched Apple driver. I had one of those drives forever ago and I know it also worked to read CDs.

I'm personally not too worried about the temperatures, since I really only use my CC periodically and don't keep it plugged in all the time. I suspect a lot of folks -- but of course, not all -- have similar habits. And even then, if 140C is the highest we're really seeing, that's still...

Well, it looks like as of 2001 those speakers were their only product: https://web.archive.org/web/20010306010041/http://www.icetechnology.com/products/index.html Here's their Contact page from 2000, it lists an address of 3982 Piedmont Ave in Oakland, with a phone number of 510-596-8883...

Can I pile on with my own CC analog board problem? I recapped the AB in my Performa 275 recently, but afterwards the machine works fine with the exception that the CRT doesn't energize. It powers on, chimes, boots, etc but the screen stays black and there's no typical CRT noises except for the...

I've replaced those parts on all of my Color Classics and I didn't notice any screen geometry changes. (Here's a Digi-Key list of the parts I buy when I recap a CC analog board.)

I've had good luck cleaning PCBs by just soaking/scrubbing them in 99% IPA. I'd avoid a degreaser or other harsh chemical, but there are a number of PCB cleaning solutions (that you usually dilute with distilled water) that can help move stubborn dirt. These are most commonly used with an...

There are 5 electrolytic caps on these drives; all have 2.5mm lead spacing, 5mm diameter and 6mm height. Not all values are being manufactured with those dimensions any more, so in some cases you'll need to lay the replacements on their side in order to fit (C104, for example). Thankfully...

I'm in for a clear resin brightness knob as well!

McMaster-Carr is both the manufacturer and retailer. Search for that part number on this page: https://www.mcmaster.com/catalog/131/3424/92525A205 Pricing is $5.30 for qty 100. If you don't care about them being stainless, mild steel screws would be much cheaper. Note that there's a difference...
