AND THE ICING ON THE CAKE IS FINALLY PUT IN PLACE!!!!!!!!
"This is a blue is almost every way, though there is something different about how the input power transformer is brought in; hence they then went with the IEC cords for AC supply on revision blue heads, though this one is a connected cord. I am having one of the guys pull apart one of my revision 2 heads to see if he can discern what, if any, difference there is at the power input transformer stage. But otherwise, it appears to be almost identical to any other blue. I think the serial number merely fall into some gray area with Bogner; as this head is apparently right at the transition phase. So, when my guys phoned it in last month and only gave them the serial, Bogner couldn't really place it. This does mean that I have another revision 2 somewhere in one of the storage lockups somewhere that needs to be found--as this should have been a different head then. Hey, just goes to show ya you should NEVER sell off amps or guitars! Oh, now I'm hearing something about how there is something strange about the bias ports, too. Geez, they're probably just unconnected ports in the chassis or something. I've got to go to see the tech dude and get this thing figured out."
