[AH] 2.0000024 MHz Top Octave Source Oscillator blown

My Hohner String Performer lost tuning right at the beginning of a 
recording session yesterday :(

I opened it up and the suspect part is a variable inductor:

Hohner part L1= BV Nr 005837

I have tracked this part down to a company called Amidon in Germany. It 
has the following specifications:

Amidon BV Nr 005837, colour code Black, Green, Brown, 5 MHz response, L 
= 19.6 uH, Q=120 at 1MHz, Anschluß an Stift A:5 E:4, 27 Euros price

Neato. I don't understand any of this.

If I want to get going now, can I not just bang together a 2MHz 
oscillator with CMOS gates?

If anyone understands these things, why would a master oscillator be 
inductor based? What benefit is it?

This thing feeds the 50240 Top Octave divider.

I checked my Crumar and it's master oscillator also sports an inductor.

The old PAIA stuff seems to mostly use CMOS gate based master 
oscillators so at least there is

So where is the question?

Ok.... has anyone replaced an inductor based master oscillator with a 
CMOS gate based one on a top octave divider based synth. I am shortly to 
do just that (as a band aid)... is this nuts?
