Maintained! This is a rare Neumann mono power amplifier for projectors. The output was 400Ω, but a custom-made matching transformer was manufactured, and 4/8/16Ω can now be used! Moreover, the power supply can be used at 100V. The input is a straight RCA cable. I can strongly feel the lively sense of power, and the rich, well-structured German-like sound. This is an item I would like to combine with speakers made in Germany such as Siemens (Daiki Goto) Maintenance information: Maintained (◎ common · 400Ω: 4/8/16Ω matching transformer added in custom-made work and made by ASSY 1 x 2 · volume cleaning repair · 10 μF other deterioration replacement 1 x 2 · negative feedback adjustment resistor 1 x 2 · SP terminal addition 2 x 2 · vacuum tube socket caulking repair ◎ No. 580224 · vacuum tube 12AX7 deterioration replacement (2026.4.27 supplies arrived) ※ Operation has also been checked with AC 100V (rated output measured at 28W SP: 8Ω) *Since this model is for microphones and projectors and has large gain, residual noise is also slightly larger. Please use the volume around the 4-5 scale. (Also, the fuse is labeled 1A, but please use 2A when using AC100V.)
