Hi again gentlemen, Been off digging about and got on to great forum. The problem seems to be the capacitors, they are the originals and need to be replaced. I have heard that marshall actually courier your amp up and down and you only pay the repair costs! Am off to email them, Will let you know how I get on. As I am on a very strict budget due to 3rd child about to appear in may (3 girls, I think I will set up home in my Vdub campervan!!) i think i will have a go myself. The only dangerous bit is discharging the caps but I have instruction on that too, (fingers crossed). Anyone know if there is anywhere local i can get a hold of such things? I presume maplin would be first call. Forum is www.metroamp.com/forum/index.php Very friendly people with lots of interest in all things amps, not just the classic brands Cheers once again guys, much appreciated. Anyone out there heard anything about the new peavey valveking head? Read a great review of the combo.
