The original design was mine and was stolen by me Ex partner Tony Relf . AC. Magnum is for Anthony and Colin. To say Tony was tight fisted greed filled man would be wrong and not strong enough to describe this moron. So the original PCB was design for a company called A.R and the artwork was stored in the same printed circuit board company in Southend on Sea called AFA,these were friends of the Relf so that how he got it. There as you maybe aware a few arse wipes in my life not including my exwife greedy cow that she, they are Tony Relf, Terry Wright and the worst of all run a cable company forced from my ownership by him and his wife and friends whilst I was ill. His name will not be printed here as the software changes mention of him to this" The same Irishman." attached is few file for info on this poor amp and the photo will show you what I mean I hope.
