Wharfedale/Rank Linton amplifier, power down problem. Schematic/service manual?

When I shut the thing off it makes a sound out of the left channel, it sound like a zipper being undone, it lasts around 4 seconds and starts off on a low tone then gradually gets higher until it gets intermittent before it finally fades out.
Any ideas?
Also, does anyone know where I can get a service manual or schematic for this amp?

I'm not sure but it seems that your Wharfdale amplifier is a LEAK Delta 70.
See the HiFi Engine library, select LEAK.

Hope this will help you.
