Selfrunning cold electricity circuit from Dr.Stiffler

[DrStiffler]

Sometimes one thinks the little MPSA06 is being pushed to hard and it gets a little hot. If you don't have a large supply of them then here is something that will work.

If you don't have a Curve Trace then just matching hfe of the same type transistor will get you in the ball park. All us old timers know that you can match and parallel, so just parallel two transistors of the same type and distribute the stress. The following image shows two connected in such a way.

Another simple thing is that TO92 heat sinks are not easy to come by, the answer is some 1/4" copper tubing, cut to 1/2" or 3/4", ream out to remove the cut edge, apply a little heat compound to the transistor, slip it into one end of the tube just even with the tube edge and crimp with a pair of pliers. Works great and you can get 12 or more from a foot of tubing, not to mention a better sink that what you can buy today.

All,
I Fired that mother up. Very early initial power up. I placed a neon across the AV plug and fired up to 12VDC or so. Neon illuminated after a short time. Tuned the inductor through full range and saw the intensity change. Will be very cool when I have a little more time to experiment with the circuit and get some good measurements. I found the spot with this rig that had a maximum output but I'm sure tweaking and adjustments will be necessary. 

Doc,
Very nice pipe, I friggin love it! It just looks good, being an old Army generator wrench! The layout tips were all incorporated in the build before any power was applied and the circuit is now operational. We are on our way!  Pix to follow shortly I just don't have time right now.

Best regards,

JIM

Doc,
The spectral density of the VLT is indeed much greater. Very interesting indeed! I can't wait to get some spectrum information on mine. I will try to get some captures shortly. I know it fires right up but it also screws with the computer monitor.    Time for a cage for my new pets. 

Best regards,

JIM

You have the show for about a week, then I will upload to YouTube a Scalar Wars video, well just how it could be done. In coming days I need to mount the VLT on a board along with another Heat series.

Sound great an hope its more fun than frustration.
