Thanks for the info there =D Yes, that was why I pointed out it might not be deemed safe! This PSU is staying with me anyway, and many of the other devices I have probably have the leads soldered from decades ago!

@@GadgetUK164 Alexey is right there. Copper and tin are both just too soft for the force coming from the screw so it losens and leads to arcing. In Germany we have a regulation that a short metal pipe has to be used and clamped down on flexible wiring, unless it is one solid copper conductor. Also what confuses me, I have three of the same A500 PSUs here and they are labelled as "5v/2.5A" with the exact same electronics inside. I even had to repair one of them because the schottky diode of the big regulator (which is for 5V) blew. So I know this model of PSU inside out. So all those decades I was thhinking the heavier transformer ones are the 2.5A types and the lighter full switchmode models are 4.5A

@@amurtigress_mobile365 In the USA its the same thing - my understanding was as well in a fault situation the wire would heat up so much its at risk of falling off the terminal as well.

I have a Hakko now, but still use the Antex for something things too.

Thanks for the info there =D

Nice idea =D

I know lol! Don't remember ever seeing a 1A fuse in a mains plug before tbh!

@@GadgetUK164 theyre usually used in Shaver adapters. 1A would be enough current, but the inrush of the transformer probably popped it

Ive just got given back my Amiga 500 from my Dad. Does anyone know what UK plug adapter would fit the bs5733 adapter to the mains. Im at a loss as it has 3 thin pins but cant see anything to marry it up. Cheers

Many years ago I went into one I think! I think they are very similar (if not worse) than the C64 ones! I might go into that one I have at some point as I think it does need recapping.

@@GadgetUK164 I would be interested to watch that episode.

In the old days I remember someone I went out with wrapping wire around a matchstick and pushing that into the socket.. and cooking dinner on an electric fire lain in its back...

blackcountryme ,,, I’m in stitches laughing,

@@briancharles3438 she was a nice girl, just a bit cavalier with anything electrical, hair tongs with the wire around the matchsticks shoved in the socket behind the chest if drawers, and smoke pouring out. Or when cooking on that electric fire, some peas fell Inthe the fire and she was using a metal fork to get them back from next to the old spring type live fire bars, not the glass covered ones...

blackcountryme is she still alive lol, sounds like a comedy sketch (quality)

LOL =D

The fuse is not to protect the appliance, it is to protect the flex as we have 32A ring final circuits which are capable of providing a massive overload. The PSU is usually fused inside with a T500mA fuse. A 3A fuse should be fitted as that is what the flex will be rated for, however 1A is not a problem

... apart from inrush current. The transformer will briefly draw more current as it magnetises. This has probably popped the 1A fuse

Thanks, yeah - I didn't calculated it, just went from prior experience of putting 3A into something like that - as we typically only ever see 3,5, or 13A fuses here in old computers. I think Peter's point there about inrush is probably why it died with a 1A fuse tbh.

Most commonly 1, 3, 5 and 13. 10A arent that common. I've only ever seen them in IEC cables

I've only ever seen 3, 5 and 13.

Wasn't aware tbh - only sized I've ever seen (and I've seen the insides of a lot of plugs in my time lol) are 3,5,13.

If it hasn't been recapped - it's well worth getting that done (and a service of the PSU in general). You could alternatively buy a modern replacement.

Voltages were measured before I connected it up to the Amiga btw!

Haha =D

@@GadgetUK164 the game just finished, I took off my headset and the TV decided to test my heart out. I swear, I jumped out of that cheapo gaming seat

Very interesting! There must be light ones in that package too! I've never seen one!

Hey Ernie!

LOL! Same here! :)

As paranoid as it may seem, these plugs have saved many lives!

Not paranoia, the fuses are necessary on a ring circuit that is rated for 32A

BS1363 was introduced in 1947 and revised to include sleeved pins in 1984. It's one of the safest plugs available. Bear in mind our ring circuits can carry 32A of current.

The schematic basically comes from an ST application note in the datasheet for either the L296 (which generates the 5v here) or the L4960 (which does the +12v). I've occasionally found the crowbar SCR dead in these too

Oh, and the 7912 for the -12V output often likes to go short as well...

Thanks =D Nah, I like to keep the originals as they are - sticking a meanwell in there is like removing the engine out of an old classic car and replacing it with a modern engine.

That's interesting! I've seen the crowbar dead in a few 3rd party Amiga PSUs over the last few years too.

@@GadgetUK164 Thats fair enough, mostly for me I think the Amiga is the part worth saving... so I generally retrofit the PSU's with a Meanwell as it is an insurance for the Amiga as well. Each to their own :) There's a few different kinds of supply.. im not sure who made this one. The switchmode ones by ISMET i dont bother fixing as they are very poor designs. There is a slim "Made in India" design which is only 22W but is very good quality. I've only come across one of the slim potted ones, made by Speedy-Tech and usually dead - I did manage to get the resin block out of one to reuse the casing!
