Hi Dean
The Waveform does look nice....
Read Steve's WEB site as well
http://www.classeradio.com/tuning.htmYou will now have to check the driver waveforms.....its all good fun really and you get to know what the waveforms are like in more detail...and gives you more things to talk about on air
Remember they will not be identical nothing is....
Check using your CRO the input to the drivers TC4422 and output without any Drain Voltage applied....to the FETs...
In this testing phase I usually disconnect from the Gates of the FETs as well...
The inputs should be around 4 to 5Volts and the output not less then 8Volts using IRF640......also check that the Power Supply to the driver is good too....power to the Driver IC's has to be perfect...
The waveforms should similar maybe one with more ringing doesn't matter really...
Then make the connection to the Gates of the FETs and check again.....the waveform at the gates should be more loaded now......but similar.......
Like here ....
http://www.classeradio.com/driver.htmCheck more then once being sure all is well......
See how that goes.........
