So much to the design-skills of Bootweaker Fran.

Harmony Central scared also: Let's nip this one right away! I am not an attorney or a judge. I have no dog in that disagreement. However, I know for a fact that other sites have had cease & desist orders served on them over this very issue, and I do not want legal action taken against HC. So I d...

Hi Lexx I ran simulation again with 5.1k drain and 470 ohm source (100mv ac signal input at 1KHz ) using a BS170 and SHO circuit. Drain = 8.07 v Gate = 1.96 v Source = 81.3 mv I am using National Instruments Multisim 10 (just updated from Multisim 9!!!). Are you using BS170 or a Jfet? Cheers Steve ...

is it not a Ross clone?

Wow, man you are right. Classic booster driving a classic Ge Fuzz face with extra controls. Probably is true what he said -- that he thought it up one night at the kitchen table. is not it more similar to tonebender mark ii? http://www.generalguitargadgets.com/diagrams/tonebender_m2p_sc_pn.gif lexx

on the Amiforum they said Langraff clean boost is copy of the SHO

yes?

@bajaman you simulate is wrong. when source resistor is smaller, dc bias is smaller also. at 470 ohms is 4,5v at drain connection
