TPU Required Reading - In my opinion

[Grumpy]

As you are so aware of the posts on this forum, with respect to TPU, what percentage of the information would you estimate to be true and what portion mis-information?

Grumpy, do you have a working TPU? Then what is your motivation for hanging around? Either you want to help others to build one or, you are trying to strand together some plausible bits of knowledge in order to enable you to build one.
Heaven forbid, the third motive is to mislead others.

I estimate that 10% of the information regarding the TPU is valid and useful.

If I had a working TPU or similar device, I would not admit it or show it publicly.   

I have already stranded together the info available and my build is going slow but steady - only a few coils left to wind and a few boards left to build.

Nothing that I state is deliberately misleading or knowingly incorrect.

For a few months now I have been trying to sift through the mountain of information on the forum to replicate a TPU. It's sometimes difficult to separate the theories and conjecture from experimental results.
I realise that there are no SM blueprints as such, and that Bruce_tpu may or not be on the right track, but least he is providing a complete picture (hopefully). His explanations seem to make sense to me.
I have so far constructed the 3 x 15" collectors. I have the various components as specified and signal generators, but my background is not in electronics, and I have big gaps in my knowledge.
How do I test the resonant frequency of the collectors? Where can I find this sort of information.
Also, I think I need to build a valve amplifier for the signals. I tried using power transistors and mosfets, but could not get pure sine wave output. Again, can anyone help.

Thanks in advance

Are you using a fast mosfet driver to control your mosfets? http://homepages.which.net/~paul.hills/SpeedControl/Mosfets.html

Hello all,

@Grumpy

I have deleted a long post to you because .....never mind.

Yes, I love to work on my coils.

I wish you luck.

@darkspeed

Thanks for the links. Questions answered.
No, I wasn't using a fast mosfet driver. Will try that next.
