F2 Set Up
 
I have nearly finished my F2 build using Peter Daniel's boards. I cannot find the thread which explains the set up and trimpot tweaking. Can anyone help?

I would also ask for confirmation that the inrush current limiter is simply soldered between the hot and cold 240v AC IN.

Thanks.

Don't think so, no!.

thermistor should be in series with tx primary. If your primary is in 2 windings of 0-120 then you can put the thermistor between the 2 windings.

Bias should be adjusted so that there is half the supply voltage at the positive end of C3.

Ed. Thanks for your reply. I did look through that thread and saw a post regarding adjusting the supply voltage, but there was no reply so I wasn't sure if that was correct. The primary winding is one 240v feed.
