And ...

It always takes more time to finish an amp. It takes a weekend to get the project started, then 2 months with only minor activities and finally a full weekend to finish my creations.

Now it is finished I can start listening. Of course I made my miles with the prototype (on a piece of wood), but I'm always nervous when the final version is being finished and listening to it the very first time.

It turned out that I soldered everything OK, no smoke and it made beautiful music immediately when switched on.

It turns out the this amp is very good, we're good friends from the start. As I do not liked to watch the transformers naked, I looked for a way to cover them up.
