C84 making helicopter sound
Posted: Thu Oct 28, 2010 7:02 pmHi, I just made the C84 and its making a weird helicopter sound -14dB. Gain is all the way down. WTF! :/
Are you getting the correct voltages in steps 34 and 35?
Are you able to adjust the regulators to +/-18V in step 37?
Are you getting the correct voltages in steps 38 and 39?
