hey

has the voltage on the signal increased on the primary when it its tapped

in the middle.  Thanks I like your videos they are very informative you are very smart!!!!!!!!!!!!!!!!!!!!

Thanks mkesharp

That is what it acts like at both ends of the primary. When one end of the primary is the most positive the other end is the most negative and Visa-Vera. And because of the center tape two tubes/transistors can drive their half of the primary 180 degrees out of phase.

continuation: The transformer surely converts impedance but does it also convert signal voltage? In the secondary there doesn't seem to be more windings to step up AC voltage. So how do we get higher signal from push-pull than from A class amp? Thank you

[AllAmericanFiveRadio]

The audio transformer is a step down transformer the primary resistance is about 600 ohms and the secondary is able 2 ohms. You can get much more details from my ebook, you can download it from my YouTube Channel.

Can you please help me understand one thing: Why do we get 'more energy' in the secondary since in the primary if both sygnals are 180 degrees out of phase -the maximum positive and negative amplitudes of both sygnal voltages on the plates are the same- Do both sygnals 'add on' to each other in the secondary?

[AllAmericanFiveRadio]

The negative and positive are farther apart at each end the of primary than would be with just one tube in a comparable circuit. More power on the primary results in more power transferred to the secondary.

oh yeah! and thanks for this nice explanation!!

[iorixs]

in built a 3.5 watt PP amp and it sounds better than the SET. it sound much more HIFI

[zbyszekskibinski]

I will do, thanks!

Mostly if you want to experiment, this can be time consuming but very beneficial in learning. The most efficient learning curve is to study other existing circuits. I recommend both.
