Blue Square Bet Premier side Tamworth fell behind after 9 minutes against Baker Joiner Midland Alliance neighbours Heather St Johns on Friday night.
A cross from the right went unchallenged and Ryan Nash headed home from close range to give his side the lead.
There was a good deal of positive play from the Lambs from then on but it took a penalty in the 43rd minute for them to draw the scores level, converted by an unnamed triallist.
The home side were eventually beaten with less than a quarter of an hour to go when Matt Watley curled a low shot from the left of the box into the far right corner to give Tamworth victory.
Tamworth`s league rivals Stockport County enjoyed a much more comfortable evening at North West Counties League Cheadle Town, running out 8-0 winners.
Craig Hobson (2), Sean Newton (2), Danny Hattersley, Darren Sheridan, John Obi-Agbo and Deji Omoboyo were the scorers as County led 5-0 at the break.
Combined Counties League side Guernsey FC were beaten 7-3 by npower League One outfit Exeter City at Footes Lane.
It was a good display from The Green Lions though, with Ross Allen scoring a hat-trick.
The visitors went 1-0 up after 20 minutes when Guillem Bauza slotted home past Chris Tardif.
In the second period, Exeter brought on more senior players and their class started to show. It wasn't long until John O'Flynn made it 2-2. Tom Nichols was the next Exeter scorer just 4 minutes later.
But 'The Grecians' were too strong for Guernsey and scored four more times before the full time whistle, with Jamie Cureton, Elliot Chamberlain, Alan Gow and Liam Sercombe all on target.
There was a decent crowd with more than 900 turning out for the game in dismal weather.
Welsh Premier champions The New Saints ended their preparations for Europe by drawing 1-1 with Conference Premier new boys Nuneaton Town at Park Hall.
TNS took the lead on 14 minutes when Craig Jones cut the ball back from the byline and Chris Seargeant hammered a 12-yard effort past keeper Neil Collett.
Nuneaton levelled 4 minutes before half-time when Jon Adams put a long ball over the top for fellow new signing Kyle Perry to score.
Evo-Stik League Southern Premier Division club Frome Town`s game at Toolstation Western League Corsham Town was abandoned after 57 minutes following a serious injury to former Frome player Dan Harvey.
Frome at the time were leading 3-1 thanks to a double strike from a trialist that was added to by another player looking to earn a deal with the Robins.
An air ambulance then landed on the Southbank pitch to take Harvey to hospital and the game was rightly called to a premature conclusion.
Evo-Stik Northern Premier League Premier Division side Kendal Town were beaten 3-0 at home by League Two neighbours Carlisle United, whose goals came from Lee Miller and Matt Robson in the first half and Mark Beck in the second.
