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

I stuck the EHT section and added a mains power supply to an old chassis from a forum member, the chassis was part of a BC1151 display section off a radar unit.

With the CRT and line transformer fitted, I could progress with more tests on the line deflection, It meant a bit more planning and plotting response curves with a used EL84. The project is certainly bringing up topics I have probably never dealt with before with electromagnetic deflection and is definitely interesting to see things work even if not perfect. Just takes me time to cram things on the chassis.

Just wondering if I can find a CRT with a similar footprint to fit the chassis, one that is electrostatic deflection for later so I do not have to listen to the transformer, perhaps it will end up getting varnished.
