i think it was in relation to the main screw of the coil touching or not touching the base plate . i'll have to dig it out and give it a read again.

Paulro I think what you are referring to is the bolt that holds the toroidal transformer through the centre to the chassis. What you must not do is connect an earth wire to the end of the bolt that is not touching the chassis. The reason of this is that it will give you a shorted turn on the transformer by connecting the bolt from the two ends to the same point ie earth. ..Clive
