Hi Tom.
Thanks for the heads up.
I'm no businessman so correct me if I'm wrong.
First, I tend to think this is good for the community as a whole - more choices is healthy for growth.
Second, technologies come and go. There will always be a better solution.
Third, most vendors are diversified. And then there are the IIGSs.
Last, I just started playing around with my Apple Iis and I hate to see any of the vendors go out of business.

Nice work! I've done a few PSU replacements in recent times, including using a couple of Meanwell supplies. They appear to be well made and I've had no issues with them thus far.
I've got a Meanwell supply in one of my IIgs machines (using the same tecnique as as one of the links you have on your blog to Andrew Webbers site), and I recently (only last week) put one in my Amiga power brick so that I could re-purpose the EOS red rocket I had been using for the Amiga in an Apple II+ clone. :-)
The EOS is a nice supply (and *very* compact), but unfortunately they appear to have rather high price tags on them now, whereas I picked them up for US$12 each!
For details on how I replaced a Vulcan PSU with an EOS Red Rocket see here:

I have always tried to fit a replacement PSU inside the original PSU case, but your solution seems quite nice too, if not as authentic to look at. I particularly liked how you used the existing holes and didn't drill any new holes to suit.
One thing you might want to consider is adding some sort of strain relief to your mains power cable. Whilst unlikely, I could see the mains cable being kicked or something and breaking free. Obviously not something you would want to happen with live wires flying about!
Cheers,
Mike

Hi Polymorph,
I have to agree the EOS are definitely compact and well-made. I got a vlt100 for about $50 not too long ago but couldn't complaint coz I was kind of late in the market. But last I checked, some sellers on eBay are asking for over $100 ea.!
Yours look like a fun project too. Are you missing the Miniscribe's whining sound and therefore not considering a CF card as replacement? :-P
Thank you for pointing out the strain relief thing. I probably did a poor job writing up this part. Actually I cable-tied the power cable from the terminals to the side of the PSU and looped it back (also cable-tied) to the back of the IIe to make it less likely being pull loose (if that's what you meant). I'll tried to make it more obvious in the text ASAP.
Hmmm, I am thinking of replacing the power switch I used with one that fits the D-Sub connector cutout just above the PSU and a thinner C6 (instead of the C14) power inlet at another D-Sub cutout to make the power connection less obtrusive (well, kind of :-)
Cheers,

Yeah I've noticed that as well. It's a pity, because these are great for fitting in tight/narrow housings.

Well, I haven't heard it whine for quite some time. I usually run that IIgs with the Miniscribe's power disconnected because it is *so loud*. I have an older CFFA v2 in there to provide storage. I probably should fire the Miniscribe up again soon to avoid stiction though. There is something nice about using period hardware, even if only on the odd occasion. ;-)

Cool. That was exactly the sort of thing I was hoping you would do. I look forward to seeing what you've done here.

Yeah, I thought the same when I saw the hanging switch. Whilst perfectly functional, I would prefer to see the switch mounted inside the //e case (if possible) like you have described.
Cheers,
Mike

Just to let more people know I had looked into the dangling switch and connector issue and proposed an improved setup here.
