[Princo]

Hi John

Thanks for the feedback, i first tried swapping the cathode connections on V2 as per the sketch, this didnt work so i put them back and swapped the o/p tx primary wires and this worked.

You are correct the tx is not an original, its a 3rd party make, all else is fine only the primary.

I will probably not use feedback at the end of the day but im very happy to understand what the problem was.

Many thanks to you and Richards help

Jim
