Hi All,

I have posted some more videos on Akula Vids

Just so as everyone is aware, I have sent requests to Stefan to fix Page 69.

Hi All,

I was looking at the TL494IN Chip again and some data on it is interesting:
                                               MIN           MAX         UNIT
fOSC     Oscillator frequency       1              300           kHz
CT        Timing capacitor            0.47          10000       nF
RT        Timing resistor              1.8            500           kΩ

Pin 5 is the Timing Capacitor Pin. Pin 6 is the Timing Resistor Pin. Akula has uses a 10K and a 20K Pots and I cant quite read the Capacitor Values. I have guessed them to be 2.2pf and 8.2pf but looking at the sheet, this may be wrong. More like 8.2nf and 2.2nf if the figures are right.

I guess the point is, Akula has half the Pot value from one TL494IN to the other which supports the idea that he was looking for the Phase Shifted Frequency we have previously spoken about. We can also see this in the amount of coil turns 13 vs 7 and also nearly half the Capacitance Values.

See Picture Below:

Hi Stefan
Very Sorry, my mistake. Sorry everyone for holding the thread up. I will be more careful with Pics. Was late and I did not pay enough attention.

All the Best
