OK.
Now, I am not sure if you know this, but me being an electronics engineer, I do know that relaxation oscillators are VERY unstable, exactly because it is so easy to change their frequency.
Typical relaxation oscillator will vary more than 10% over relatively narrow temperature range and power supply voltage...

Now we just have to explain, why pulsars are so stable? Because, the change in pulsar frequencies are minuscule, compared to those in typical relaxation oscillator (in terms of ppm). Also, those changes are occuring very rapidly. This also needs explanation/modelling.

However, this was not my question.

I want to see the description of that oscillator of yours - how it works.. I want to see the (equivalent of ) "schematic", in other words.
Or, I want to see the precise description of mechanism of this oscillator: from where the energy comes from, what is this that oscillates and how. Where is the feedback path?
Also, I know how to calculate the oscillation frequency of the circuit consisting of two transistors (or even valves... the first oscillator I build myself was with ECC81) and couple of resistors and capacitors.
I want to see the same type od calculation here. And of course, I need to see some examples.. and how those calculated results relate to observed specimens.
Until I don't see it... I simply can't take those ideas seriously.
