samuelcroberts Posted July 16 Share Posted July 16 (edited) Hi Guys, I have a Genz Benz Shuttle 6.2 head that I've used for ages. Has been a backup for a while now, but plugged it in the other day and something is awry... Basically a very loud white noise/hiss is constantly present when on, even when the input is muted, so definitely something going on in the amp. Gets louder if you turn up the master. Has anyone else had a similar experience? Is it worth fixing and, if so, does anyone have any amp tech recommendations in the Birmingham area? Cheers!

BreadBin Posted July 19 Share Posted July 19 Check the valve is properly seated, my Shuttle 6.0 did this and that solved the issue. 1 Quote Link to comment Share on other sites More sharing options...

agedhorse Posted July 19 Share Posted July 19 It may be that the valve is not seated properly, but it could be other things as well. Where are you located? Quote Link to comment Share on other sites More sharing options...
samuelcroberts Posted July 21 Author Share Posted July 21 Cheers for the replies, guys. I am away this weekend, but will check the valve and see if it fixes the issues.

samuelcroberts Posted July 22 Author Share Posted July 22 Opened it up and, although it looked like the tube was seated properly, gave it a wiggle and the problem is fixed. Cheers guys! 2 Quote Link to comment Share on other sites More sharing options...
