I need a advice for a stereo amp, help needed!

Boscoe · 27th July 2010, 09:15 PM

Basically I'm on a bit of a budget but want a stereo amp at least 20Wrms into 8ohm and powered at 24Vdc as I have a lot of these power supplies and don't have the budget to buy a new decent one when I have this amount. the thing is I want a kit one don't ming wether it's pre built or not i just can't find what I need. The LM3886 to power humgry for what I want and dosen't go on 24Vdc but great price and avalibilty. The TDA2050 from sure electronics, great power great price right voltage buts it's from china and I can't wait a month for it. The velleman K8060 amps from maplin good price, but wrong voltage although I have a torodial I can use already, it's just enclousing these and cooling them well enough. I'm thinking of the TDA7377 as it is very easy to make but I have no PCB equipment and can't find any kits. Theres a lot of amplifier kits out there but I can't find many from europe althoguh I only really want to buy from the UK. Thanks a lot just wondered if someone had any suggestions.

Well I can tell you from experience that stuff from china doesn"t take a month .... Ive gotten stuff from sure electronics in under 10 days , it is actually quicker from china than some places within my own country .....

Another option would be to etch your own PCB (you don"t need anything specialized accept for a lazer printer and an iron ) or even easier use vero board and source your own parts .....

Cheers
