Thanks, i double checked with another list from a german forum - errors in both lists but combined it was very helpful

if you want to correct your list:
R1 is wrong, 220 is correct , not 22.000
R94 is named wrong, correct is R84
Quantity of C2 and C13 is 2, not 3

Dangit! I already placed my mouser order....maybe I can dig up 2 220r resistors in my toolbox.

Thanks for finding that. I will fix and update.

Carl, which value did you order for the input DC-blocking capacitor C1?

The schematics in the "Builder'S Manual" that I sent you, shows C1 with a value of 10F.
As I have been told, the highpass consisting of C1 and R3 + R4, results in a 240ms time constant. That gives a F-3dB = 0.66Hz.
I have never tested, if the SYMASYM can handle frequencies as low as these.

A 3.3F, even a 2.7F DC-blocking capacitor will do it as well.
The PCB accomodates for capacitor grid-sizes from 5 - 27.5mm.



Best regards - Rudi
