This question might be best to ask Mike Brown.
I am using two Peavey Nashville 400 amps and a Peavey Pro Fex II. When I turn them on I get a loud several loud pops and also when I turn them off I get a loud pop.
Is there anything I can do to stop this. Sometimes it is not so loud and others times it is VERY loud.
I have the same problem with my Nashville 400, and I think the problem is the powercap’s C 63 & C64 ( 4700uF 55volt ) and C66 & C67 ( 1000uF 35 volt) are bad, I did not have the time yet to replace them but as soon as I have the replacement caps I will let you know the results
