1. Do you have an oscope?
2. Is the MOSFET stone cold, or getting really hot?
3. Is the threshold control working?
4. If the MOSFET is warm but not hot or cold, and the threshold adjusts correctly, and you have no oscope, lick your finger and start touching various parts of the circuit, starting at the input to the preamp and working your way to the output. If you suddenly start getting an audio response from doing this, it may help narrow down where the problem is. An oscope is best, but I often use this method as a quick-n-dirty check.

Hello everybody,
I post from south of France where I live.
I am on the way for building the HH release D. Most of the components are soldered. I need to get the missing ones at the end of the week.
Please, could you give me the link for the adjustment procedure ?
The PCB from Silverdog is really well built.
Sorry for my mistakes in writing English.Comment

Here is a link to a short video. It basically shows that it works but I did not demonstrate any adjustments.
