Opinion on these PSU designs

[Clocky]

I recently came across these replacement power supplies for retro
computers made in the states for their market but also available as an
Australian version:

http://personalpages.tds.net/~rcarlsen/cbm/universal_ps/

and specifically

http://personalpages.tds.net/~rcarlsen/cbm/universal_ps/AMIGA%20PS.jpg

Is it just me or is the A/C input fuse way too close to the case which
think is metal. Other construction issues (I think there are a few).

Issues selling this PSU in Australia in terms of needing certification
or anything?

yeah, that does look close, with it that tight I'd expect to see
fire-resistant card or plastic between the fuse and the case.
but the case is grounded so any short circuit will not conduct for long.
also perspective may be making it appear closer than it actually is.

Only if you get caught.

the guy who assembled it seems to have soldered to terminals instead
of using the apropriate plugs.

If it's of any interest the board in there could be a
"Mean Well PT-65B" retail price less than $30

Yeah true, I'll quiz him on it. Perhaps there is something stuck to the
inside of the case.

I would have used the correct plugs or taken the extra five minutes to
desolder the plugs and solder the wires directly to the board.
Those glass output fuses should be in those plastic insulating housings
for mine, but maybe that's just being picky.

It is, thank you for your comments.

Care to elaborate as to why they are dangerous in your opinion, toaster boy?

So no worries there then. But obviously resale wouldn't be allowed.

Hmmm. So the Amiga PSU that's been taking up space in a drawer for decades
might be worth something?

Probably not, there is a reason why people are looking to replace them.

I thought that it might be that they are worn out after decades of use? The
one I have was part of the whole kit and kaboodle that I got as part of a
job lot, still in a huge display box with polystyrene insert and all
peripherals that worked perfectly and had seen little use (mouse feet not
worn at all, no dust....). It looked for all the world like a rich person
had bought it, possibly for a kid, who then found little to no use for it.

I kept it for a while but then moved house and, after trying unsuccessfully
to sell it, offered it free on a couple forums. When there were no takers it
had to go - but I kept the PSU as I often find myself in need of a DC source
and thought I might re-purpose it. 10+ years on I still haven't....

Not so much that, it's mostly that the caps fail, and that is a bigger
problem on supplies that *don't* see regular use. On some, like the
A1200 supply, it is filled with resin so repair isn't even possible.

I don't know what model you had, if it was white and quite compact it
was likely an A1200 and they go for $250+ quite regularly on Ebay today
and you certainly would have had takers 10 years ago. OTOH an A500 10
years ago was worth bugger all - they're worth more now.

Is the power supply white or a kind of cream colour (and quite large?)?

I'm fairly sure it was an A500. However what I thought made it more valuable
is that is was in it's original large display box covered with cheesy pics
of the whole family having fun with it - and there were brochures, pamphlets
and the original documentation. Also it appeared from the original list of
'what's in the box' everything was there, in pristine condition (as well as
a couple optional extras including lots of programme and game discs).

Yep. Commodore Power Supply P/No 312503-05, S/No 0990.

LOL, when I went to find it just now I see I still have a Commodore 64 PSU
as well. I guess it's time I threw these things out.

Oops, I deleted your other message. Instead of throwing them out you
could put them on ebay or gumtree and get a few $ for them.

Better to recycle than dump isn't it?

I've tried that in the past - in fact I tried that with the A500 complete
set with a $10 reserve. Not much luck previously but I might try again.
Freight is the killer with low-priced stuff. :-/

Oh very much so. That's why I still have them, hoping to find a use or home
for them.

Yes, and getting more expensive all the time. Amiga 500's were a dime a
dozen and are still cheap, but the A500 power supply is a better
alternative to the standard A1200 one as it has better output and is
repairable so you might do better selling that by itself.

Connectors are the same, so nothing to modify.

You would surely find someone on the Lemon64 or LemonAmiga forums to
take them as there are a number of active users on there from all over
Australia.

My fault, I just assumed ;-)

I think you will find some active Kiwi's on there too in any case.
