Sheriff,
Your Curriculum Vitae is 'impressive'. I think at the time I built my first amplifier (Tubes) you were not even born

My occupation/hobbies are the same as yours, I'm a musician since 1975. I started computing around that time and still do !As well gigs, recordings, equipment repairs etc.

Please try to respect other people's opinions/views and be a little more kind in your replies. Etwas mehr freunlichkeit und ein weniger Hochmut würde besser passen.

Grüsse aus Holland !
