I would like to show my lattest project. I used the Velleman k2573 kit as a basis for making my own phono preamp.

I changed the resistors with metal film precision types. changed capacitors with foil types and the input and output capacitors are directly mounted to the RCA plugs (MKS4 types)
If building this kit. buy a NE5532 in stead of the TL072 op-amp. That's doesn't make the overall cost.

I've also been advised to de-couple the + to - op-amp rail. This has to be done this weekend.

Here are some pics for giving some building ideas. I kept it very clean and simple. No blinking light. Analogue sound in wooden box!

greetings Steven from Belgium
