It was 2014 when we last made these, we have now made another small batch to restock and they are now available. Cost £16 plus postage. Simply email sales@sharewareplus.com for more information. We have had the adjustment rod professionally milled/ manufactured in brass and these are now available with the knob for £6. A special thank you to Frederic (e5frog) who has recreated the plastic support, these are now available, with three m2 15mm screws, they are £5 each. Updated 1st January 2024 The wires are soldered as shown, if you have a different PCB let me know and I will send you the alternative soldering points.
