Technical walk-through and demonstration of spark generation from my first dual resonant Tesla coil. I finished this dual 811A vacuum tube Tesla Coil back in late 2008, which dates this back 15 years by now! At the time I finished this coil, my best camera at the time, could only record in 640×480 with horrible […]

The latest update to the 100 Watt 6P45S tube amplifier is about a lot of testing and fault finding that have gone into the tube amplifier. This is to correct noise and hum issues. It is now in a state where the audio amplifier itself is as stable as it will get. Further improvements lie solely on

The latest update to the 100 Watt 6P45S tube amplifier is the measurements of frequency response from square waves and bandwidth measurements. The prototype is now considered done as it has proved itself capable of outputting 210 Watt peak before clipping. At 100 Watt peak it have its -3dB points at 11 Hz and 72
