JHS Mini Bomb troubleshooting

Just put this together and there is a huge amount of noise. Whats interesting and hopefully helpful is that as you turn up the boost pot noise goes from no noise, steadily increasing with signal volume until near the end where it starts to decrease and isnt that terrible by fully CW.

Gate and source are at 0v, drain is at 4.4v.

No schematic?? Ah, a Falstad run....


What is "noise"? Hiss? Hum? Buzz? Toilet gurgle? Bagpipes?

But in general, when "noise" is worst half-way up the pot, it is getting into the wire from the wiper.

Tyty what software did you use to draw that?

Definitely a buzz. Bagpipes wouldve been welcome.

So would that mean faulty transistor? Or should i try a new pot?

The link you gave has a link to Falstad circuit simulator; you did not see that? I just grabbed an image while it was running.

The WIRE. Is it long? Goes bad places? Is the build in a metal box?
