Hi, I have tried alot to find information on these 2 particular tube
amplifiers made by Orange. They are a british company who makes all
tube powered amplifiers. Their homepage is www.orangeamps.com That can
get you started with that I am talking about! The names of these
amplifiers are.... AD200B MK1, & AD200B MK2. Basic info on them for
you.. its a 200 watt tube bass head all handmade, point to point
wiring. To help you with what places I already know... I have the
Orangeamps forum covered( I am a member there), and their website. I
also know about the Orange amp feild guide... Besides that,
information was very sparse. What I would like to know about them is
how many were made of the MK1, and MK2. What is the difference between
the 2? If possible would you be able to find the schematics( diagram
of the wiring layout) for these amps? I hope you have better luck
finding information then I did, because I was at it for a WHILE!
Thanks!

Cedric
