It was my first tube amp back in 1980 when i was just a teenager.
You can see her on the picture below (my first concert ever).
The hand you can see is of a friend of mine, which was doing some kind of human clean boost, pushing up the volume for me when i was playing solos.
After some years of use the head had problems, she stopped working, so, instead of taking her to a tech, i would put her in the cellar of my friend drummer of the group, and almost forgot her there.
At this time in 1991, we bought a new Rose Morris Vox AC30 with money hardly earned by playing gigs (still own the Vox today) and forgot about the Orange.
I think the explanation is that we didn't care too much about gear in those days. they were just tools to make music... Or maybe we just smoked too much.
Anyway, time passed and one day in the beginning of the nineties, my friend gave the head to his young nephew, and he bring the head to his home in Germany and had it repaired.
Finally, last week, after almost 25 years, i traveled to Germany with my old mate, 1000 kilometers from my hometown, in order to bring back the OR100 to France, and here she is, cleaned a little, just waiting to go and see the amp doctor....
The tubes :
2 Mullard ECC83 preamps
4 AEG EL34 . I don't konw if they are the original tubes
Here's what Watford says about that brand :
"A.E.G was the company that formed out of the demise of Telefunken. It carried on producing valves for a number of years under the A.E.G brand name. We believe that these were made by Siemens Germany due to the valves construction. This valve is a fantastic audio valve providing balance detail sound with good bass. In small guitar amps such as Marshalls and W.E.M the distorted sound is both large and rich."
