I use the values from the notes, not the schematic and have always built with j107 and 5102 or whatever the match is. I use mje350 and 220pf caps. On the shunt I run 8.2 ohm 5 watt non inductive wire wound five watts and heat output is modest if you use a 300mA choke regulated power supply/ pre regulator and stick to 25.5- 26v under load into the shunt.
Slav I think I have a spare quad of those 8.2 ohm resistors. Ill include them with your coils if I can find them.
Don't forget to lift that 100k before you plug them into your paradise. That 27r need only be 250mw, use a good metal film.
