Default 1st diy amp kit

Hi can someone recommend an amp kit that is good for a first timer.
Also recommend a good power supply that will work with it.

The budget is around 100 (160 USD)
My source is an Arcam Rdac and my speakers are Monitor Audio BX2 that require 30-100 watts at 8ohms 90DB

So far i was looking at something from Chipamp.com or DIY Chip Amplifier Kits, PCB's, Components and Information.

Many Thanks
Mark

You can't go wrong with Peter Daniel's kits. Just add a transformer. The Antek is about $50 shipped. regards

On the antek website its $44 just for international shipping is there any other uk options.

And what is (in terms of sound quality) the difference between a LM3875 and a LM3886

Sorry, I did not look to see that you were in the UK. Try a local supplier for a 22-25v xformer. I prefer the 3875, a little less powerful but I think better sounding. Regards BTW Peter may can help on UK sources for a suitable xformer.

I built a Peter Daniels' 3875 amp and am very happy with it, especially for the price. Plus, Peter was very helpful during the build. A
DIY Chip Amplifier Kits, PCB's, Components and Information. gets my vote.

Hi MarkL1

You could try Airlink for transformers in the UK. The ones I have bought in the past have been very good quality and were delivered quickly.

26 pounds seems to be about what an Antek 300va would cost here in the states. Go for it!

It works out at just over 40 delivered which is good but which one will i need the 300va 22+22 or shall i go for the 25+25??? Also im definitely going to go with an audio sector kit as they seem very popular and theres lots of stuff on the forums to help me.

Also is there much difference between the classic and the premium kit? is it worth the extra money??

Thanks to everyone for all your reply's i really cant wait to get started!!

I build the premium and I was happy with quality! These LM3875 kits sound very good, but use at least 10.000uf per rail in the power supply. they come with "joke" caps for power supply.
