Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

The TONE and PWM outputs are over attenuated on the ColorMax.
The PWM is so low as to not even drive a CMOS scmidt trigger.
I would suggest simply removing the 1kOhm resistors to ground
from the final out. It wouldn't hurt to lower (or short) the
4.7kOhms, but the main problem is the final (fullfrequency)
voltage divider .
