I posted a thread in the pictures forum about these amps (with a brown band around the neck), so if you want to see the pic of the amp you can look there. Anyone have Omnas right now that have an expiration date that is later than 6/2011? PT did some looking for me and his results were pretty much that the brown band on the top is not something that anyone he checked with has seen. The potential exists that these are brand new and they changed the amps, but that is just a guess on all of our parts. Does anyone have Omnas with a later expiry date than what I listed that do NOT have a brown band around the top of the amp? Thanks.
