Dear Sir:

I´m a Telecommunications Engineer. I worked some years working in engineering companies. Later I became a professor and this is what I do nowadays. I also collaborate with Vigo University, studying man-made impulsive radioelectric noise as a doctoral thesis work. But I like to make some electronics too, as a hobby.

I found your issue A75 very interesting and I decided to make it. As I made some slight variations, I decided to include some comments to your article which are interesting in the way of a particular implementation of your design, specially the last stage connection and heatsinking.

I send you this work with some photos included, waiting for your answer about if you consider it interesting enough to publish it on your web page.

Yours Faithfully:

Pablo Torío.
