Here is the video. Lights were turned off to show that series bulb does not light up. The one that looks like a second bulb is a reflection.

I think the problem with using Tesla is the low Q of the primary. I still need big currents to power the primary and will be looking for small changes. Is there any circuit that requires very low currents once the high Q circuit has developed a very high voltage?

Well, a Tesla primary has a low input impedance (and not a low Q)  because the primary coil has a tuning capacitor in series with it and at resonance a series LC has a low impedance. This is why a relatively high current is taken from a source that drives the primary. Some tinkerers use choke coils between the HV source output and the spark gap: this can limit the high current and also can protect the HV source output coil (which is in an NST) from the inner arcing, see this link: http://www.sky-chaser.com/tcpart3.htm 
A series coil, labeled as L1 is also used in Richie Burnett's  circuit here http://www.richieburnett.co.uk/operation.html

You can take ideas for making the coupling between the primary and the secondary as shown in these videos on the Kacher circuits: http://www.youtube.com/watch?v=yOwsEKN4S8Q   and   http://www.youtube.com/watch?v=4NVib5S_oGM 

Perhaps the Brovin-Kacher oscillator is the simplest circuit to maintain the oscillations in a (secondary) Tesla coil.
A good schematic on it is also shown at 2:10 in this video: http://www.youtube.com/watch?v=xMiNnHzFsRQ

Your 100W+ power op amp build is surely a useful effort to enhance the output of a signal generator, however, you have to make circuit protection means to defend the op amp when any 'sparking' may get back to its output, even accidentally.

IT is okay that you consider the bulb test as successful, as shown in your latest video,  however I hope you understand that such series lamp tests do not give any useful info on the in/out power ratio, (whatever spectacular they are) because you do not know and so cannot consider the input impedance of an AV plug with which the input indicator bulb is in series. (As I wrote earlier, the power taken out from the HV source (whose inner impedance you do not know either) is divided between the series bulb and the AV plug.)

Excellent info again, thank you Gyula.  I will read and tinker for a few days and see what Ican come up with.  Regarding the 'success' , yep, its amazing, but I agree. I think of it as some impedance transformation where high voltage , low current is converted by the cap to a lower voltage, higher current.  Perhaps not technically correct but along those lines.
