Default Hello

Hello to everyone, I'm from Portugal and i have a growing interest about homemade amplifiers.
Actually I'm studying electronics and telecommunications in the University and i'm just in the first year so I don't know a lot of electronic/electrics but I think I can learn something with all this community.

My actual "dream" is to build a amplifier and respective PSU all homemadem with no bought kit's in the internet.

Ps.:My English is a bit rusty and bad trained, sorry for that.

Thank you for your positive evaluation of my English, but mozilla dictionaries help me a bit.

Hello Russo, Your English is much better than my Portuguese. In fact, it's better than the English of many Americans!
I pretty new here also. It's nice to have other newbies. I to am studying for my Electrical Engineering degree, although I'm a little older than most students. I also have an interest in designing my own amp.

Good luck and have fun!

Dave

Well I have thought about a LM3886 based gain clone and respective power supply based on a toroid transformer and some mur680 rectifiers.

I have already made some searches in the forum but the chip amp section doesn't have a lot about this chip.

Default Amps

Once upon a time I was young and very eager to build things,such as amps and home made speakers, by buying the drivers and crossovers and so on, only to realize after hundreds and hundreds of hours, that it was cheaper to buy good quality hardware for cheap. More than 20years ago I 've purchased Crown (studio quality amp and ADS speakers also reference series and I did not have 1 repair an any of the products. It sounds and works great, never mind the fact that there is no way I would be able to afford these items at today's prices.
But I have to admire you for the efford you are trying to put into this project.
Good luck

A majority of us do it for the fun and challenge - not for the cost. Personally, I enjoy building audio gadgets as much as I enjoy listening to them. I wish I had more time for both
