Improving the Borbely Servo 100

carlmart · 21st September 2005, 10:57 PM

Last week I started to think on the idea to do an "improved Servo 100", that could perhaps start from the original Borbely project but not going to the DC100. It would be important eliminating the servo, though still retaining the principle of no cap on the feedback.

Has anyone modified a Servo 100?

Going over past threads I could find that Dave S did some work on that project. If you are there, can you elaborate a bit more on what you did?

Having some amplifier that use the same thopologie, and also, if you can informe the components values, will be very good to see your unit.

Thank you in advance Carlos

regards,

Carlos

Carlos (Martínez),

IMHO these, especial driver circuits, are of the best that have ever been designed. I would suggest the DC-102 (Audio Amateur 4/93).
