Is this what you're saying the collector should be like.  See attached drawing.

Please explain?

Hi Dan,

I can answer that question very easily, and everyone here please hear me out! Look at the picture of the SM17.... Look at it!

You can clearly see that the collector coils in the big TPU don't go around more than one, otherwise that gap wouldn't be there! Mr. Mark did describe the collector coil as more like a band then a coil, so that would explain that.

Look at the picture of the cut TPU. Those dots in the middle between the upper and lower part could be all the collector coil wires. Another possability is that the collector coil wires are at the top and bottom and the middle is just filler material.

Dansway,
Yes, that is what i had in my mind..
I must be careful not to be misleading ..this is My vision..and not directly from the master... but ottos test seems to confirm it...
as does mine...yours?
There could be many different ways to weave a tpu.

Might it also add that it appears the two collector coils in thart TPU are directly connected to the two toroidal transformers on top of the control box...

Mannix i think I had mentioned this in an earlier post. In a tube set the plate inductance to the transformer is most important that saturation doesn't occur when it dose the electrons start flowing on the outside if the wire because the tube has no where to send them - the transformer being in the saturation state the Field in the gap gets overloaded and then the transformer gets saturated on the outside in witch a large E-Field develops ---if the power is not interrupted there could be other forces that take place . i still feel the gap in SM large TPU is an air gap of this nature.
