why do you think that. I believe the control circuits are separate to the sound?
I also live in France and the hassle of sending this back to the UK is not to be undertaken lightly. The last bit of kit was a 4 month turnaround. A local dealer? If only.
Yes I know they won’t affect the sound. I think only the factory can do the control circuit work but it may be worth giving Darran at Class A a call. What POTS revision is yours?
