Default Re: 5FP7 project starting with the focusing coil.

The project has been tidied up slightly, fitted the scan pcb within the front of the case, protected fingers by using some aluminium panels to keep finger tips out of HT. A small 50Volt mains transformer, bridge rectifier and cap used to supply the focus coil, fed via a variable resistor.

Lastly started with some horizontal scan coils for the frame side of NBTV and a bit of testing deflection with the bench power supply.

Still a long way to go.
