Ashdown VU on Max!

[richukuk]

Hi everyone,

I turned my Ashdown ABM 500 on last night and there was a massive hum and the VU meter is stuck permanently on maximum. This is without me even plugging in my bass. The hum is only on with volume and gets louder if I turn up the volume. Does anyone have any ideas what is causing this please? I've tried different sockets, leads, disconnecting speakers etc

Thanks!

Update, I have tried it again this morning and it is working apart from until I turn on the Input EQ and then I get a loud hum. The VU meter is still stuck on max too.
