The switch you need is made by Marquardt 1802.6123 - I bought some recently from Mouser Electronics. Appears to be the original part.

Thanks Ants - I was not aware of spa peroxide and from the pool shop it looks a lot cheaper than the hair stuff, and of course is much stronger! I should get around to mine.

Was serious about the modelling part - if someone sends me a clip, I'll produce the model.

Making the model isn't really the hard part, but printing can be with something that small and complex. I don't suppose the side resting on your fingers is completely flat? If so then it looks like it could print without supports and that orientation will lend itself to a strong print, where...

Congratulations, I had one of these monitors and the repair manual - I though disassembly looked really hard!

Congratulations to everyone involved, that's great work.

Congratulations on the new Mac - for those broken SIMM clips there are some neat 3D printed clips to help you out. I believe you will find them on thingiverse. If you don’t have a printer, just ask (and say where you’re located).

I would not want to submerge a transformer into an ultrasonic bath. It may never correctly dry. Just too many layers and gaps for liquid to sit.

What a magnificent device, I wonder if it came from a need to write Japanese characters?

Nice!

I split the analog board/power supply part from the main project and I have published it now - https://github.com/aeberbach/MacSE-SE30-analog-replacement Have fun and I'm keen to know what you use it for! If you're in Australia and you want a PCB, let me know. If you're elsewhere then getting...

I'm working on this. Getting a replacement power supply is actually easy, Mean Well make two or three modules providing 12V, 5V and -12V, then the -5V rail is just an additional 7905 regulator. So now I have a replacement power supply board that mounts one of these modules and replaces the...

Congratulations! Definitely a great 68k Mac.

Thought I would mention this here since it can be hard to find decent fans in this size. The "Gelid" available on Amazon for example, is not a good fan - it's closer to 16mm thick than 15 and is expensive! But I found this fan available on many of the large distributors: Sunon...

Congratulations, that's an amazing find. I hope it turns out to be good inside!

I would not expect anyone with a functioning Mac to want a CRT. In some ways it's an improvement but go further down that road and you may as well emulate. The idea is to avoid this situation of unobtainable flybacks and CRTs and all the rest.

When I owned a cube back in the day the LED was the only thing that required replacement by Apple. I suspect some kind of capacitive effect when in the shell. I don't have one to look at but are there any components in or related to the LED that you could replace, electrolytic especially?

I was using an Altera but I really prefer the Xilinx tools so I switched. I'm working on an Arty A7 board (Digilent) now. Resources weren't much back then - things got harder though, I need to do clock reconstruction now to avoid having to take the 16MHz clock off the logic board. I really just...

I have a replacement plan in progress - LCD screen, replacement "analog" board with no more analog, FPGA to process/display SE or SE/30 video. Depending on a board coming back this week I might be done with all the LCD power requirements and now I am writing FPGA code to manage the LCD. I've had...

I tried sealing a flyback in a monitor that was buzzing and sparking once - it was fine for a few weeks and then one night flames started coming out!
