Tommy Taylor's shock resignation proved no problems to Conference South high-flyers King's Lynn as they felled hosts Bishop Stortford 5-3 at Woodside Park.
Taylor's decision to quit for a backroom job at League Two Peterborough was soon forgotten as the Linnets raced into an early lead.
They even missed a penalty, Chris Wright saving Mark Warren's lacklustre spot kick before taking the lead in the 26th minute.
Adam Smith broke the deadlock, curling in a free kick from the edge of the area but the Bishops - managed by former Arsenal striker Martin Hayes - hit back.
Roy Essandoh, a one-time Cup hero with Wycombe, levelled from Dave Collis' free kick and Danny Morgan put them in front.
But that served only to shock the visitors, who hit back when Wright fumbled in an Adam Smith free kick for a soft equaliser.
And in the second half the managerless Linnets raced away.
Michael Frew added a quick-brace on the hour to put the visitors in command and Matt O'Halloran put the game beyond doubt when he gleefully headed in a Frew cross on 71 minutes.
Alex Martin's late deflected shot proved only a consolation.
