For sale is a pair of vintage Siemens/Klangfilm tube amplifier module, originally part of a German broadcast system. This unit features dual ECC83 (12AX7) tubes and the renowned T55/2 output transformer, delivering warm, balanced tube tone. With level (Pegel) and symmetry (Sym.) controls, it was used for precise signal amplification. It was removed from a fully working unit and is in excellent operational condition. Perfect for collectors, restorers, or custom preamp projects. A rare piece of audio history!

Thanks for watching
