I've got a PF500 I bought used, so therefore technically without a warranty. Now I have the dreaded fault light on and nothing else...seems to be a well documented issue on here. Hopefully Ampeg acknowledges that..has anyone had any luck getting Ampeg to fix under warranty when they didnt actually have a warranty? I am used to GB customer service, and they would have taken care of this in a heartbeat. I sent Ampeg an email, let's see how where their morals lie?
