Nice pdf doc Alan, good reading and pic drawings.
 
Something about this is telling me I have to figure the right loads.
The last test had 1.5-1.6v AC output.
To run the tubes I had to use diodes, and it would not work with added chokes.
 
Before I redo another testing set I'm looking for 1.5v loads.
The indicator lights I used are 12v old automobile indicators.
 
The coils and core are like a musical tone instrument. Several tones can be heard at one time while tuning.
On my PWM are 100k precision pots and they can tune! The MEG actually produces several notes like a lick in pefect pitch.
Although there are some ugly tones I get several notes in succession that are perfect arpeggio's.
It likes to tune to its resonance.
 
When I used a autotransformer and bridge for the coils it makes a hissing tone sound, it does not like this second source.
Maybe that the PWM does not like the other negative wire of the autotransformer?
I couldn't get the autotransformer over 15v setting anyway.
15 volt primary seems that this MEG likes that.
 
I need to think of 1.5v load sources (cheap), any ideas?

put more and more loads .

call that guy of yours .

Never give up .

Thought I would write a small update on my MEG1.
 
It seems I am having primary voltage power issues that need some modifications.
Electrojolt sent me a power supply mod I will have to incorporate it.
 
Other tests have shown positive results looking for over COP1 but not there yet.
Some of these tests have shown me that I can load the secondary's up and see the current on the secondary's rise and no current change on the primary.
But..... as I load the secondary (with resistance) the voltage on the secondary also drops.
I have not found any good loads other than lamps.
 
So 2 things I have in mind, power supply mod (for more voltage) and or rewire my secondary coils.
I believe I need more turns here.
 
I'll have to leave this sit for a little while as I am working on some other old unfinished tube project.

Would it be possible to make this work by powering the control coils with common AC, the coil would have it's magnetic poles flop back and forth at the AC frequency, though not as sharp as a squarewave, I am wondering if this would still be enough to flop the permanent magnet flux from side to side through the pick up coils.
If that would work it would be a lot simpler to set up, just put 60 Hz in and get 60 Hz out at an increased wattage, thoughts?
Otherwise, how are you doing with this thing? It looks awesome :)
