GLD 80 screen rotary issues

I have an early GLD 80 and am having issues with the knob at the bottom right of the touchscreen. It seems to go slower the faster you turn it and is hard to use now. Is there a replacement part available for this? If so, how difficult to replace is it and where might I find it?

Thanks

As this knob is probably one of the most stressed parts of this desk beside the faders you should contact A&H support for spare part and repair procedure.

Please give a report to this forum how the repair was managed cause i think this will be of general interest for all gld owners.

Second this post… I’d like to hear about a fix for this. Takes 10 minutes to roll up a certain number!

I was just about to ask about this problem! Anyone else having this issue?
