I see several totem pole connected JFETs.
Additionally, without the JFET datasheet, it is impossible to determine the required Vgs biasing, but most certainly will be several volts.
With the minimum information provided, I would say it would be difficult to bias it correctly with only a 9v supply.
Do you want to power it up from batteries for portability? Why not use a boost converter? There many available at Ebay for a couple of Euros.
I know, they are noisy.....but you can always add lots of post filtering.
Now, if a boost converter is not an option, why not use a pair of A23 batteries? A little thicker than an AA, but 12 volts.
