They have been quite cheap ( ~ 0.6 EUR) just a few (< 5) years ago. Now they are not available any more. Looks like it is good to invest in such parts before they are not availble any more.
On the other side, the SMD parts can be used as well, just a bit more effort. Like the BF862, http://www.iup.uni-heidelberg.de/schaefer_vlf/VLF/BF862.jpg

Greetings all,
Storm "Friederike" has taken her toll - the enclosure of my VLF6 had a small crack, so water slowly crept in, which slowly killed the high impedance input. It's in for repair now. Hope the FETs survived - I'm slowly running out of stock of these ancient J310 devices. 

Hope to be back soon.
Cheers,
  Wolf DL4YHF .
