Used Lectrosonics IFBT4 Transmitter in good cosmetic and technical condition. Minor casing wear and mounting scuffs from studio rack placement. Backlit LCD screen, XLR jack, front switches, and rear BNC antenna port are completely clean and operational.

Testing: Bench-tested. Verified 250 mW RF output, audio modulation via XLR input, menu navigation, and pilot tone squelch response. 

Pulled directly from a professional, climate-controlled, smoke-free corporate broadcast facility. All units have been tested, factory reset, and are running stable firmware. Expect minor cosmetic rack-wear/scuffs on the outer casing, but front panels and technical functionality are excellent.
