Strange plug advice needed

Postby tc99 » Wed Jun 20, 2018 9:49 am

Hello

I bought an amp of ebay, should have checked the pictures first, as it has a non UK standard plug on. From looking around it looks like it could be Italian though it says "Masterpiece England" on it, and Italy is 230V, whereas this is 250V. Here it is . .

any ideas what it is? will a universal adaptor sort it out? seller is none the wiser (says was her husbands)

Cheaper, and probably a lot better, to cut it off and put a proper 13A plug on it rather than mess about with an adaptor.
Is it captive at the amp end? If not replace the whole thing?

I agree with Kwackman. If it's a detachable cable, chuck it and use a new cord with a proper 13A plug (suitably fused). If not, cut the current plug off and wire on a new 13A plug -- making certain that you wire it up the correct way around, obviously!

It's difficult to tell from the picture - it could be a Type-L which is used mainly in Italy and Chile; this has the three pins in a line.

Image

Or it could be a Type-N which is used mainly in Brazil; this has a centre pin slightly offset.

Image

But - as others have said - either cut it off and replace it with a good 13A plug or, if it has a detachable IEC type cable, replace the complete cable with a moulded one. :thumbup:

A quick web search shows it to be an old UK designed and made plug that was designed for powering Hi-Fi separates.

Cut off and replace.

Well spotted Wonks. I thought it looked familiar, but couldn't place it.

thanks guys

it is fixed lead into the amp . . yes i said to my dad i should just cut it off and put a standard plug, but he thought there may be a problem fixing a new plug on, i can't remember the exact reason (i'll have to ask him again) . . he's ok with this things, but not an expert, so i think it should be ok.

you've done well to find that Wonks, i came up with next to nothing when i looked on the web. Thought it might be some specialist adapter thing.

I have a feeling i may up just sending it back, as if the woman who sold know nothing about the plug, so i doubt it was even tested before sale.

Seems silly to send it back because of the plug. When the amp was new it would probably have been sold without a plug and the buyer would be expected to know how to wire it up. The first couple of pages of a typical instruction book from that era would show you how to do it. Just unscrew the existing plug and fit a normal 13A plug with the appropriate fuse (probably 3 amp).

James

i'm ok changing the plug. The problem i have is if the amp itself is not working, if i have changed the plug i can't return it. I'm just trying to find out if the seller had tested the amp in the first place before selling. She says it was her ex's, and has no idea what's going on with the plug, so i doubt she even tested before selling. It's probably ok, but i'm not sure i want to take the risk

As it's a removable plug I'm sure you could take it off, connect the bare wires to a choc-bloc, and wire in a proper 13A plug and cable just for testing. If all good, remove choc-bloc and fit proper plug, if not refit the original plug!

It's a re-wirable plug (it's not a factory fitting), so if you fit a normal plug (which is perfectly reasonable to do as you won't be able to use it without doing so), then if the amp doesn't work, you can re-fit the original.

For a very quick and careful test you don't need to take the plug off.
Get one of the larger sizes of choc blocks and separate three 'slots' . Fit them on the individual pins (the middle pin should be the earth, but check in case it's been done wrong) , then put three ordinary wires in the other end. Screw up tight and cover with tape. Fit standard plug to free ends.

If all is OK, do the job properly straight away. If not just remove the 'adaptor' and send the amp back unmodified.

For what's worth, doesn't look Italian. The three pins have the same size in italy, while in your plug the central one is longer.

You beat me to it Wonks,

I had all my hi fi gear rigged on something similar for years. I guess now that everything comes with a moulded 13A plug peeps don't want to chop them off as it would invalidate any warranty I suspect.

Shame because it did make for a compact and neat powering solution.

"Back in the day" we kept a couple of 13A to insulated croc clip adaptors around the W/S for just such non-standard plugs...But we won't go into that!

thanks everyone, i will give it a go, and if there is any problem i will just re-attatch the old plug. I really don't think it has been tested, but she has decent feedback on ebay, and it is in top nick visually. it's one of those 90s NAD amps, and they are a decent make.

cs70 - yes, it's not Italian, but specialist for UK for hi-fi.

Dave yes, it can see it would make a nice tidy up with this size, with hi fi kit plugs, can see why it was made.
