This is my first post. My english is bad.
I want make a amplifier that must to be: - simple and fast to assembly (good kits or universal board, ....); - have good sound (better of my Nad 302); - good for listen classic, spirituals, country, ....; - working with 89-90db speakers (I don't know the power necessary); - very cheap; - well bjt, fet, chip, t-amp, .tube, .... Give me an idea? Bye, Francesco |

This new 100watt amp might be worth a try, and he can deliver complete supply boars, easy and safe

Hi,
using cheap as the most important criteria, then you can remove tube from your options. Chipamp or very simple BJT could get what you need. For 89 to 90db/W/m speaker try for 50W to 100W. If your speakers are 8ohm then lm3886 might be your solution. Small PCB and low component count= cheap, kits= easy to build, Have a look at some of the chipamp threads, Nuuk's Decibel Dungeon and look at the ESP site.

Thank you for reply.
This project is well but it isn't cheap. I don't need 100w, is excessive for my listen. Bye, Francesco |

I use 40-50watt...but there are different kinds of 50watt, and my small monsteramps are no doubt much more powerfull than a small chipamp
"41hz" have some interesting amp kits, and quite cheap...personally I dont know them The 100watt from AussieAmp may also be configured as a 60watt, lowering the voltage

Without knowing, fore you I would say "Amp10" looks interesting with onboard supply and ordinary hole mounting, meaning easy easy to build

i found simple, and low cost.
http://www.audiosector.com/lm3875.shtml the dual mono classic: $57 (can be run off a transformer with dual secondaries) add appropriate transformer(s), available from various places, something local. look for ones with 24v taps and between 150 and 300VAC (if these numbers are wrong, someone correct me please) the rest is the basics. potentiometer, power switch, Mains jack, RCAs, etc. and case, obviously. -Jared |

Thanks.
I'm undecided, T-amp way or gainclone-way. Which is better? Which has better sound? I don't know t-amp and gainclone sounds. Bye, Francesco |
