Hi
My Quad FM4 tunerhas stoped working on channel. ( I think this may be connected to the damage to the circuit board when the battery leaked ) I am planning to check out the problem but wondered if anyone had a circuit diagram that they would be willing to post.
Thanks
don

Andrew,
The Quad FM4 has a 2.4 v Nicad for Memory backup these usually leak out onto the pcb and makes a nasty mess.
Don,

The Quad FM4 has a 4.8V memory backup battery, not 2.4V. These days it and IC1 should be replaced by the new battery-less IC1 from Quad.

I'm sure he isn't, but this is a site of record, and plenty of other people will be interested, and errors should be corrected, not left to stand forever. It's not a chat site.
It is now 
I think, it is this device:

the same issues by such batteriy/accu than in Linn's KAIRN - go to
