RE: SR-52A rebuild project (SR-52A 942058 LTA4176)
I have decided to make a new keyboard for the SR-52 as my keyboard has lost too much of its conducting ink traces. Spent a wholde day of measuring (everything in inches instead of mm). I used the schematic/diagrams from Jose Mesquitas. So I do hope they are correct Smile

As the currenct PCB is 2,2 mm thick I willl redesign the supporting frame between the main PCB and keyboard in autodesk inventor and 3D print a new one as the common JLCPCB circuits are 1.6 mm thick.

Next step is to try to get a 100% correct size pcb diagram out of my laser printer first, glue i on some cardboard and verify the measurements are correct before sending it off to China.

Until the next post
