My falcon board that you had last year had these problems with delay on. All before the 100K resistor was installed. I then resoldered it to delay off and sent it to you. I did a bit of testing on another Falcon. With your Colckpatch (delay on) but without 100K resistance almost the same problems as mine. Then 100K resistor soldered in, sound problems gone, DSP test program all green.exxos wrote: ↑Thu Jan 27, 2022 9:24 pm Looking at the files for my buffer patch V3 (not yet produced) , it seems for some reason I added another delay to the "DELAY ON" thing. As it was about two years ago I cannot really remember why Running a quick simulation it seems I increased the delay by 10ns.
There was a post in the German forum were reporting that the delay on was causing problems. Maybe @kohli79 was involved and can remember ? I cannot remember if this was on a stock machine or not ?
I might have increased the delay further to mimic the gated delay on the Phantom. But by all accounts, the delay is probably not really needed And could be creating problems.
At this point I am unsure if to leave that on the board, the delay and the extra delay
But after 2-3 hours under load/stress, reading errors occurred. After soldering to delay off it was gone and everything was stable!
I had already written something here, penultimate post.

From the German Atari Home Forum. And yes, the Falcons were original without accelerators etc.
