Update: taking on board the replies I've had we do more checks on certain component and as Derek said it ended up as a couple of faulty TIP36c's. Replaced both on the PPB along with the coil, coil sleeve and diode on the VUK and now the game is working great
Thank you to all that replied and a BIG thanks to Blair for the detailed PM's
I've only been a member here for a short time, but this is a great site made up of top people who are all willing to help out anyone where they can, why would I go anywhere else.
Cheers Mark.
