aria ad-10 analog delay

[Hefty]

Working on a aria ad-10 analog delay and wondering if any one has one, had one or knows anything about one?
I know this is long shot but hell we went to the moon right. Any owner manual or schematic would help.

So I have most of the issues with this pedal fixed, but have one left. When I first plug in the power cord and start playing, the pedal bypasses the guitar like it is suppose to. As soon as I activate the pedal the delay works and if I use the switch for the second function and  hold down the pedal switch and activate the second setting on the delay every thing works as it should. but once I activate the pedal the go back to bypass mode the delay stays on no matter what. If I unplug power the bypass works again the first time and then after delay stays on always. So the pedal uses a surface mounted 4069U for switching between modes. Also 2SK30a JFETs for switches. Is maybe the 4069U have an issue or any other ideas.
