Home Brew High Voltage Power Supply 270V DC & 6.3V AC eBay Bargain!

I've had a bit of luck on eBay and picked up a rather promising looking home-made High Voltage Power Supply. This power supply looks like it should do 270V DC and up to 70mA with a separate 6.3V AC filament supply for working on valve/vacuum tube equipment. In this video I'm going to have a look inside to make sure all is good, check it powers up ok and give it a bit of a load test.
