Yusynth VCA problem

Hi, I breaded the Yusynth VCA using 2N904 transistors, I'm pretty sure everything is in the right way. I've bread boarded it a few times now and I'm pretty sure my wiring is correct, but the audio is too low, like I can barely hear it. It isn't trimmed properly but even when I adjust the trimmers it doesn't improve the problem. I'm just about to switch to a different VCA if I can't get this working. I've looked around the forum and it looks like other people have posted about a similar issue but I haven't been able to fix it so I'm posting again Very Happy

The leads for the 2N... transistors are reversed from the BC... transistors. Did you check this?
