Adrian,

the schematics as shown in the Builder's Manual is the current one.

I have prepared shopping carts from the German distributor REICHELT.
I will send the carts' URLs to you via EMail in a minute.

Please use 0R1 emitter resistors.

Best regards - Rudi_Ratlos

Any chance to have the schematic with better resolution? Sometimes is hard to read values of different components on the manual schematic.
Thanks and happy DIY in the new year !

what exact type of resistor did you guys use for the FC100 ?

did you all go with the Yageo Metal Film Resistors (Professional) Type MF0 Series ??

Michael, wrong thread! I generally use YAGEO Metall film resistors.

I never heard them (I mean the name).
What would be their advantage vs excellent resistors such as Dale (with attention on series), Holco and PRP (of which I have seen distortion measurements and several positive opinions)?

first problem is, that i cant find all values with PRP / Dale / Holco which are needed.
second is, PRP has a to big footprint with 0.5W

I haven't ordered anything for my FC100 yet, but it seems strange since Vishay/Dale has the most complete range, maybe they werent available at the time.

Speaking of resistors, in your opinion there is any possible issue using parts with looser degradation over time PPM >=100?
For a different project I have used some RN55E which are of such type, while being still a 1%.

jep. i can`t find a 2R2 Dale at any distribution i know
and RN55 is way to small it has to be 0.5W that would mean RN65 - but then you have the wrong footprint.
so its not that easy as it seems!
