I read that, but the top waveform on page 13 doesn't show that. So much for accurate pdf's I guess. :( > Also on the first page: > "In all cases, a low level state on the PWM pin will turn off both the > LSA and LSB switches.

Anyway, I have 2 of those coming, and 2 of the 420 watt audio boards coming, and 1 150 watt audio board coming. The audio boards will need to have the input caps replaced by a wire jumper, and possibly even a bias summing point for best operation. They are also buckets faster. > > > On Oct 18, 2020, at 4:28 PM, Gene Heskett <ghesk...@shentel.net> > > wrote: > > > > On what page do you see that, Thaddeus? > Thanks Thaddeus. > _______________________________________________ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
