How does it sound when connected to polish pi ?

Been playing with online language converter, so did the polish pi for fun, seems to be fair conversion.

tell us the damping resistor value Carlos.

[Carlos]

1K

[kt315]

change on 560 ohm and show the pics again.

Tengo el potenci?metro con una resistencia en serie y veo la forma de onda a medida que giro el potenci?metro y esta es la mejor curva de ca?da que obtengo, en todos los casos giran alrededor de 1k

I have the potentiometer with a resistor in series and I see the waveform as I turn the potentiometer and this is the best decay curve I get, in all cases they revolve around 1k (Translated)

[Mr.Jaick]

why the coil is underdamped (I guess) ?
what's the advantage?
i haven't seen this approach in any other designs

The 560R image shows an underdamped waveform. The 1k resistor image shows even more underdamping. I would guess that the correct damping resistor value is 470R.
You can see in the 1k image that the preamp saturates to the negative rail during flyback, and then saturates to the positive rail before decaying to 0V. The correct value should make the preamp output saturate to the negative rail, followed by a smooth decay to 0V. The bottom line is that 1k is too high, and 560R may cause some instability.

Wonder if it an underdamped wave form. Scope looks like it's on 50us/div(maybe not?). Wonder if maybe a target signal?
