Tamworth have secured contracts for four players.
Coventry striker Shaun Jeffers and Barrow forward Vinny Mukendi, both 20, have agreed one-month loan deals with the Blue Square Bet Premier club.
Midfielder Michael Girvan, 19, has been without a club since his release from Wigan in May, and has agreed non-contract terms with the Lambs.
Fellow midfielder George Baldock, 19, has re-signed from MK Dons on a youth loan deal which runs until 31 December.
Baldock made three appearances during his loan spell at Tamworth last season and has recently returned from a stint in Iceland.
