Replacement knobs in the UK in Helix Posted November 5, 2021 Just following up on this thread, If anyone needs any spares in the UK: Sontec (Electronics) Ltd, Sontec House, Concorde Road, Norwich, NR6 6BE firstname.lastname@example.org +44 (0)1603 483675 http://www.sontec.co.uk/Parts My new volume knob and replacement expression pedal plastic washers arrived today. Approx. £15.96 for knob and 3 washers, which I thought was reasonable. Then I looked at the figures on the invoice. Before the VAT the washers were £1 each, the knob is £1.30. They charged me a whopping £4.50 for postage and £4.50 administration fee! What a rip off.
