Hey all,
I know theres alot of info on here about the motorboating issue some federal AM864's have when being modded or when they are not calibrated properly with the current control. I have built a handful of Am864 circuits and only have been able to work around motorboating issue when dialing back the current control, leaving stock attack and release times and changing the cap in the SC to let less low frequencies through. I would just like to know why all these changes make or break the opporation in a Vari-mu federal.
I look forward to learning from you all.
Thanks for your time!
