Mark Jones led his side to a 46 v 20 victory over Risca two years ago and will once again lead Ammanford hoping for a repeat performance on this bank holiday weekend.
“It is really exciting to be going back,” said Jones.
“We were fortunate to get here two years ago and win, but there are a lot of new faces in the side now so it’s going to be a big day for them.
“Leading the team out at the greatest stadium in the world is a fantastic honor and it was an emotional day for me.
“I have told the new boys this year to make sure they sit back and take it all in. It’s a day you will always remember and everything goes by so fast.
Ammanford reached the final following a 58 v 26 victory over Gorseinon in the last-four while their opponents, Glynneath beat Tondu 16 v 3 in their semi-final.
Glynneath play their league rugby a division below Ammanford but captain Dale Newell believes even though their opponents may go into the game as favourites, Glynneath need to focus on their own performance.
“We have worked really hard so to get here is really well deserved,” he said.
“They will go into the game as favourites, they have been here before and are top of the league above us.
“But we know we have the resources to win and we simply have to go out onto the pitch and play our own brand of rugby.
“We have played some good rugby on the way to the final and it’s a fantastic feeling knowing you are going to be playing in the national stadium.”
