Replacing a valve in an Ashdown amp

[paul j h]

Hi All,

I posted in another post about my amp having an annoying hum when using he drive control. After some great advice on the forum and from Guy at Ashdown amps I have bought a replacement valve for the preamp.

But here is the problem, how do I get the thing opened to replace the valve? sorry if this is a silly question, but I have looked around and can't find any means to remove the metal casing to get to replace the valve.any advice?

What amp is it?

Ashdown Klystron 2 x 10 combo

On the top of the combo are screw covers. The little black circles. Pop them off to reveal screw head.
