I appreciate the fast replies!

I have it working now!

I landed on C33 at 160pf. I also swap the BBD's with each other (of course I don't think that actually did anything). Re-biased and auto probed.

Finally mess with the cancel trim for a long time with the amp cranked to try to hear and cut down the noise as much as possible. I found a good setting almost 3/4 of the way up.

I'm guessing Scruffie was right and it was my poor adjustment of the cancel.

Thanks for help guys! Just got it boxed up.

So I have my aquaboy deluxe built and calibrated and it sounds great!

I built using the V3205 V3102 from small bear.

Only problem is I can't seem to get the max delay time to the advertised 550ms without a high pitch squeal. Best I've managed is to adjust the clock trim down to about 420ms. thats the highest delay time I can get with out the squeal in the background.

Ive consulted the troubleshooting section of the build guide with no luck. The troubleshoot part of the build guide said to replace the delay pot with one that came in closer to spec (rather than under) I canged mine to one that comes in at 1.06Mohm. Also per the guide I have changed the value of C33 (and re-biased the BBD when necessary) many times to different values with no luck.

I really don't need the full 550ms, but I have to have at least 460-470ms. Any help would be appreciated.
