Comparing Class T Amps

[Mysteryman]

Can anyone confirm size of plug......is it 5.5mm outer diameter and 2.5mm inner?

Maplin is probably the quickest, unless you don't mind waiting for the post.

Yup , if you find an old charger with a suitable plug you could cut the cable off. I have some 2.1mm and 2.5mm DC plugs which I can give you if you PM me your address . You'll have to solder the cables on mind.

Yep, at least according to the supply they link to on ebay.

Right, thanks for all replies and suggestions, which came in while I was firkling around in garage looking through box of chargers/adapters.

I have found a couple with 5.5mm plug on and will be able to snip off the wire and use one of those - job done!!!!

The wire is only flimsy - like bell wire - does that matter or would I be better getting a plug and using something a bit thicker?

I used a cable from an old PSU in the first instance and bought some plugs and made up my own cable later . It's a Bantam Gold I have though , so not sure which DC plug you need for the T amp.

What is the output in amps of the charger you took the lead from?

[Mysteryman]

Err, 95mA!!!!!

I have now taken up Brian's offer of a plug and will make up a lead using some decent cable!

Final question (until the next one!).......

Does the positive from the PSU go to the centre of the plug?

What is the output in amps of the charger you took the lead from?

[Ali Tait]

Yes, centre is positive (it almost always is). A good idea to make your own lead, that offcut may have been too small to carry the required current.

[Mysteryman]

Many thanks....over and out!

That's enough to fire the amp up and test that all is working, but it will run out of puff very quickly with such a small maximum current output.

Maplin do a small 2A switched mode wall-wart charger of around 12V output, I seem to recall.
