Aion Convex help

[jfrios]

Just recently built the Aion project for the Dinosaural opticomp and although it seems to work fine i.e. Effect and buffered signal pass, voltages seem correct, I noticed
that the level of the compressed signal seemed very low. Started messing around with a scope and meter and noticed that the circuit sounds just the same with or without the
2n5088/2n5087 transistors (I used sockets, tried different transistors same result, the transistors are getting power). Any ideas?
