**Update**
i have managed to source a second hand Mark Levinson unit, for a decent price as well! £120 + postage which was £10, I checked fuses 4 & 12 as previously recommended by @Steve thanks mate, and sadly no fuses were blown and even after changing them, still no luck. So I went for a second hand Mark Levinson unit, it arrived today, I'm wondering whether to do the replacement myself or pay someone to do it, it's a simple plug and play then I am.anle to do this myself, does anyone have any ideas on the difficulty of this job, or any links to tutorials I can use, or any advice you can throw my way?
Thanks,
Mitch
