This mod is mentioned in the A-101-9 user's manual on page 14. R4 has to be
replaced by 1M and the vactrol connected in parallel to the new R4. R4 is
the 100 k resistor next to the pins 8/9/10 of IC1 (TL084). I can send you a
copy of the A-145 silk screen directly if you send me an email
(hardware@doepfer.de).
