Hi Frank,

    For those with a less advanced understanding of electronics (such as myself), what are the advantages of this circuit?  How does the field effect transistor work and what differentiates from the ‘regular’ transistor?  What is the thyristor semi-conductor and what is that doing for us in this circuit?

    Thank you so much for these educational circuits with descriptions, they are really so helpful.  Especially since 99% of the Lectron System manuals post 2001 are all in German!
