PCBs to build a Turntable Speed Measurement device

I have just completed this project and can strongly recommend it. Works great and an essential for fine tuning an idler drive, specially a Lenco.
George generously and patiently assisted me in finding the one wrong resistor I installed. Didn't stop me from lifting a couple of pads and making more problems for myself.
I configured it with an off board sensor and display. Ended up with the fuse and power plug as well. I had a 4 pin mini DIN plug for the sensor cable but it proved to be a poor connection so I removed it and hardwired. Be careful with the 7805 reg heatsink touching the base of the diode!! The fuse works luckily.
