8 LM3886 200W per channel. 600VA 27V and 240,000 uF. I think I overdid it with the caps, but oh well, the more the merrier. Overall, very nice sound, no hum and very very small hiss at the tweeter at about .5 inch.

Really nice!

If I may ask, did you base your design in the National application notes?

It is similar. Some things i changed are taking out the buffer and my own method to adjust the offset voltages. I also have some output inductors in there.

Folks:

When I made the offer, my 13 year old daughter jumped at the chance to help me build a small integrated amplifier for her bedroom. She did about half the work (including assembling the BrianGT boards and most of the other soldering). We used an extra HiFi2000 chassis and Front Panel Express cut, engraved and colored the front and rear panels. The amp sounds great, she's happy and we had a little bonding time (very important, for reasons all parents of young teenagers will appreciate). All in all, a great father-daughter project.

Regards,
Scott

Scott,

Absolutely splendid work. FPE is awesome isn't it? I use them all the time. Please give a huge pat on the back for your daughter. Its nice to see more females get into a hobby that is very male dominated

Best,
Anand.
