Hello SDIY friends,

I have an ARP AXXE the is giving me hard time...

the problem is in the ADSR.

if the Attack slider is about 5 mm higher than the Release slider, the
ADSR seems to works.

if the the level is about the same or A lower than this offset (5 mm)

the ADSR is always  on (like a VCA open)

there is neg voltage that is leaking in but I'm not able to trace it

on TP4 I'm getting from -6 to lower voltages

To clarify:
A) CV and GATE signals are correct
B) connectors are clean and firm
C) I changed the 2 lm301 of the ADSR circuit
D) checked all Caps in the area
E) checked trannies
F) the VCA is closed and only the VCA with ADSR is high

thank you for your help
Antonio
