Another older design by "La Maison de L'Audiophile" was using half 2SK240 (Idss 2mA), R in-to-gnd 100 ohm, 2 kohm on D, S connected to gnd, 1uF o/p cap (no R to gnd) and +12 VDC (Lead Acid Battery bypassed with 10.000uF elcap).
For 2SK240 with higher Idss, they suggested to add 47 ohm from S to gnd
For 2SK240 with higher Idss, they suggested to add 47 ohm from S to gnd
Thank you that is exactly what i image. very simple. One problem though cannot find the fets in stock. Does anyone have some clues?

Gain x10, how many dB 20?
@Salas
How many dBs?
20dB=x10 times. 30dB=x31.6 times. 40dB=x100 times. 50dB=x316 times. 60dB=x1000 times.
20dB=x10 times. 30dB=x31.6 times. 40dB=x100 times. 50dB=x316 times. 60dB=x1000 times.
I will print, another lesson than now I know, thank you Salas.
If need 26dBs can I add other SK170BL in parallel?
20dB=x10 times. 30dB=x31.6 times. 40dB=x100 times. 50dB=x316 times. 60dB=x1000 times.
Is there a formulae for that calc ?
