Orange OR100, first owner, letting it go as I have made a different amp purchase. This is 230V bought in Australia, switchable to 120V.

Ruby Tubes are still going strong, has been serviced professionally. Never modded. Used by bands such as Monolord, Conan, The Sword, Ghost and Helmet. This thing is LOUD. Only aesthetic affecting marks are on top from having amps stacked up, there are some techniques online to remove them. See last two images for closeups.

Switchable between 2 and 4 output tubes as well as full and half power. Very handy for different sized rooms. Cleans are beautiful and warm and the dirt channel goes from 70s rock to crushing metal and doom. Footswtichable Gain Boost and Global Boost. Happy to throw in the footswitch to the right buyer.

Open to shipping but will be at buyer's expense. This head is very heavy (23.84 KG (52.139 lb)) and I'd prefer not to try and ship it overseas. I have had success shipping amps through PacknSend etc. interstate in Aus, I will remove all tubes, bubble wrap and label if this is the case.

From Orange:
From the off, the OR100’s classic vibe is evident, with its ‘Pics Only’ fascia paying tribute to our ‘Graphic’ models of the early 1970s. However, whilst the tones within are certainly at the vintage end of the spectrum, the OR100 caters for players searching for the ‘Holy Grail’ of ‘old-school’ British tone but with modern functionality.

This amp is the first model in the OR Series to feature two channels. The Clean channel is a non-master type, with a tight low end, plenty of headroom with a distinctive and unmistakably Orange character. The Dirty channel has three stages of gain, rich in upper harmonics, taking the amp from Classic Rock into vintage Thrash territory.

With a huge dynamic range, defined note separation and wealth of colourful gain textures the OR100 also features a valve buffered effects loop plus a switchable output section, varying the full 100 Watts down to 70, 50 and 30W. For added flexibility, the OR100 also sports a footswitchable gain boost on the Dirty channel, plus a footswitchable global boost which adds 3dB to either channel for an extra kick when you need it.
