I have been told by CJ that when they perform the upgrade that it is the same as an original "A". However; you may wish to contact them and ask. They are a great company to deal with and I am sure they would be more than happy to answer your questions. Also if you are in doubt about an amp that you are considering buying I would get the serial number from the seller and ask CJ to verify that it is an "A". Again hope I could help.
