[R-390] 6080 in place of 6802 - RMS ???

[Roger L Ruszkowski]

Fellows,

I follow all the logic in these arguments and see Zero Point Energy Here.

If we push an AC voltage across a diode to develop a positive pulse we get
more than 1/2 the available power on the far side of the diode.
If we push the same AC voltage across a second diode to develop a negative
pulse we get more than 1/2 the available power on the far side of the
diode.
If we filter the positive pulse to a DC average and
If we filter then negative pulse to a DC average the working power
potential between
the two DC voltage is more than the input power.

Put all the good miss applied math away and understand you do not get more
out than you
put in.

If you argue that the DC pulsed power out of diode is greater than 1/2 in a
positive polarity
then you must accept that the DC pulsed power out of diode is less than 1/2
in a negative polarity

If you apply 12.6 volts to a diode and 6.3 volt filament in series the
filament sees the correct power whether the
diode provides a positive or a negative pulse to the filament diode
junction.

If you apply 25.2 volts to a diode and two 6.3 volt filaments all in series
the filaments see  the correct power whether the
diode provides a positive or a negative pulse to the filament diode
junction.

The tube change in the R390 power supply regulators works.
Using a diode in the 3FT7 socket with two 5749's works.

In each case two 6.3 volt filaments are placed in series with a diode and
powered from 25.2 volts (or what ever it says in your text).
The diode blocks 1/2 the power. 1/4 of the power is dissipated in one tube
filament. 1/4 of the power is dissipated in the second
tube filament. The thermal cycle of the tube is longer than 1/60 of a
second and the filament yields a near stable source of
heat for the tube cathode. The one 1/2 of the power blocked by the diode is
a true power not used. In the original circuit the
power was converted to heat. For the 3FT7 ballast tube the heat provided a
voltage regulation function. For the R390 series
regulator tube the heat was wasted in a pair of tubes that did not work by
design to the tubes full capability.
