Aquaboy DX - No more Delay

So I built up the Aquaboy DX (V3205) last night and got it all setup and dialed in.  Good sounding delays.  I boxed it, tested again, still good sounding delays.  I went to play through it today, and no more delay.  I still get bypass sounds and when the pedal is on, still clean sounds.  I am using V3205's for the BBD, V3102 for the clock and NE570 for the compander, all powered by a 9V One-Spot.

I went through the troubleshooting on the build doc, and got clean audio through pin 7 of the compander, and clean audio through pin 7 of IC3.  I double checked my jumpers and they are set correctly, with pin 1 of the BBD's at 0V, and pin 5 getting 8.17V.

Funny thing about this is that I built up a Dirtbag Delay with V3205 chips and had the same issue happen.  Works great for a day or two, next day its done (I haven't resolved that one either).

Do you think it could be a case of bad V3205's?  Its just very curious since the same thing happened to a Dirtbag.  Maybe its something I am totally overlooking, a part that I added that I shouldn't for this kinda powering.

Here is a picture of it boxed up (when it was working last night)


Thanks for any help in advance

Voltages look okay, i'd audio probe.
Works at Lectric-FX

I can't tell from the picture whether if you put a D1 or not
