I have just acquired a Quad Elite Hi-Fi system which belonged to my late brother. The speakers consist of 2 x L12 Studio Monitors + an L2 Sub Woofer.
I have connected all the components & the system works fine except for the Sub Woofer which will not switch on. I have checked the fuse & it is ok.
I have had a technician check all the power circuits & everything is good.

He checked the sensor on the Heatsink & it is showing as an open circuit, which he says could be causing the unit not to switch on. He asked me if I would post this thread to ask if anyone has a circuit diagram & parts list & who would be kind enough to share them with me.

I am aware of the security & ownership of repair manuals, but would really appreciate your help if possible.
I still have a working Quad 33 / 303 combo which I bought new many years ago. These units are in need of some TLC & updating.

Regards
Alan
