I wish my dad could build me an amp It looks great, hope she likes it.

How does it sound? Do you like the snubber?

Also wondering about the tone controls, can you post a schematic?

Thanks,

Josh

Shematic used is from the National datasheet for the LM1036

The snubber is a 0.1uF across every diode, didn't try Carlos
(tm) snubber yet. I used standard parts, and the quality is much better then commercial amps which would cost the same or more.

The whole build was something like 75 Eur, but I got the transformers cheap, only 7.5 Eur a piece (24V 80VA).
Case and heatsink I got nearly for free from a local scapyard.

Barely, she is 8 years old. But she knows how to operate it, especially the Volume...

I absolutely, positively second that!!

Giving children the means to appreciate music is the best thing!

My only comment about the amp, and it is MINOR, is why was the volume put in between the tone controls?

Why not in a logical order Bass, Treb, Bal then Vol or the other way around?

I will build one for my 9 and 7 yr old... As of now they each have crappy portable(boombox) players that they listen to EVERY night as they read before bed.

This made the printlayout more easy. If you want to see the layout, have a look here:
