Brett,
I've got no experience with those aftermarket power supplies...I've always managed to rebuild mine but thankfully were not EuroHacked tm...But I'm sure Beaky will be able fix it.
But - I do however have PinScore displays in all my Sys11 games (3) and they are very high quality and I wouldn't hesitate to put them in more....Even better now we have a local supplier of their products too.
