Doesn’t need much introduction. For sale is my Quad 405 (2) Power Amp. The reason for the (2) is that this 405 has been fitted with quite late 405-2 boards, so is to all intents and purposes a 405-2. Why so cheap ? Well, it sounds great and is 100% functionally working; it just looks a bit tatty. By no means a car crash of an amp but has a few marks here and there.
