Ok no problem thanks GK.

GK,

I can confirm 150v spikes, however I believe these are normal spikes at the collector of the transistor.  I confirmed this by removing the feedback from the collector coil and the spikes remained the same.

Can you disconnect the collector feedbacks and see if the spikes disappear or remain?

I can also see spikes across the collector coils of 100v, but if I load them with a very small 12v bulb, they go flat and the bulb does not light at all.  There is no power in them.

I have not seen any heating so far.

D can you tell us what youve done, specs that sort of thing, so maybe GK, can see anything amiss.

Hi Dom,

There is not much to tell so far.  I have built a TPU as close to GKs as I can.

I have connected to it a 3 555 timer generator like GK and tuned through, nothing special.

I have tried a Seike oscillator (self fed 3 phase) I have tried white noise and I have tried a logic circuit which provides me with perfectly sync'd harmonics based on the input frequency.

I have attached a 4 channel digital thermometer to measure the TPU temperature in 3 locations and the last probe to measure the room temperature away from the coil.

I have measure the power in the feedback circuit, the 12ohm resistors in Ottos diagram, I have loaded the collectors down with various loads.

So far I have seen nothing I have not already seen.

I dont think I need to list anything further since I am not making any claims, just that I have made an identical TPU with the instructions given and I have seen nothing.

The tripple 555 timer circuit works very well and the PCB was kindly sent to me by Alex (GroundLoop), but its lowest frequency is 3.5Khz and GK has been testing around 10Hz.

So, next I have to connect my 3 independent function generators with some drivers to the TPU and hope that then I can see something nice.

Dave.
