I have an SR7EHD-21/27 power supply that has been traded in from a customer upgrading to SR7EHD-21/27 XL power supply. The power supply case is silver anodised.
I would be looking for £380 for this, including the DC lead, plus the insured shipping costs. Buying this new with the 10% Art of Sound members discount would cost £625.50 plus the insured carriage and packing cost, so it is a very good price. There is still 22 months parts and labour guarantee left for this power supply. Sorry no AoS discount with this power supply.
Regards
Paul
