Are you still after a quad? I made a mistake last week, playing a cornford MK50 mkii. Wow! So the quad and lonestar special may be offloaded to change.
My Quad has been serviced in last 3 weeks and is 240V. Casing looks scuffed as you would imagine but all working. For what it's worth I have a custom switching box which works on an A/B principle. A=Lonestar Special Combo as standalone unit, B=Quad routed through lonestar power amp section only but with solo/boost option.
