I'm goin to convince my mum 2 buy me a PCB starter kit coz i really wanna get into making amps and other electronics, but i dont no wot i should make first! Does any body have a good simple schematic of a basic amp not to complex they could send me?
i post all my progress with pics and stuff
plz help this newbie

Hello Sord,
Maplin mostly do Velleman kit amps now (which I've never tried). I built a couple of the 150W MOSFET amps a couple of years ago which are nothng special (except for sub usage) but are very easy to build. There's some build details here:

Nice one,
David.

maplins website is www.maplin.co.uk. There is should be PCB development stuff under COMPONENTS AND CABLES on the product menu.
its a kit, it does also come pre built as well but you pay more for that.
the link is here: http://www.maplin.co.uk/products/module.asp?CartID=030131153718795&moduleno=32295&modulecode=
most of the infomation is there
EDIT:
reading the infomation, you do not need a powersupply kit, just a transformer which maplins sell, you will need to read the instructions for a sutable type.
this is a sterio amplifier which has 2x10W output in 8 ohm
you will need a 50VA 2x12v 2A transformer for this

i've built it!
hopefully its right
the instructions that came with it were very brief so got a pdf off google with better construction guide
its says use grease between the heatsink and ic but does that matter?
plus can i use a standard wall adapter to power it?
pics will be on tonight

wow that was quick.
the thermal greese shouldn't matter as i doubt the ic will produce much heat - but if the chip feels too hot to touch then go and get some, a tube of it is only a few £'s from maplins.
im not sure how you can plug it in, if you point me in the direction of the PDF i should be able to help

no, you cannot plug it into the mains, you must purchase a 50va 12v transformer - you can purchase this from maplins, and it should be quite cheap.
- on page 6 there are powersupply options, i recomend a toridal transfomer as they produce less interferance but nomal laminated iron core transformers are cheaper.

Sord_Fish,
you are asking people to give up their time to help you. Do you not think it would be polite to take the time to write your questions in correctly spelt (and typed) English? Not only is it extremely irritating to see you mangle English, but for those members who are not posting in their first language it must be incomprehensible (they were certainly taught correct spelling and grammar). It may be acceptable to text your friends in this way, but not here.
Good luck with your amplifier, and be careful. Electricity kills.
