MFE - TA 300 SE Röhrenverstärker

With a high damping factor and enormous power reserve, this amplifier effortlessly drives any speaker. The no-load stability also makes separate operation on a subwoofer possible. The tubes are built into the housing for safety reasons, but the front plate of the amplifier is equipped with a bronze tinted glass to still enjoy the glow of the tubes.
