We really were amazed with this very small and light piece. As with most tube electronics, rectifying hum is at times a challenge but the device has proven well worth the effort. We really never did any physical restoration on the Gott and finding an owner's manual was impossible, even after a trip to the County Library. This required really close listening and monitoring with proper speakers instead of just turning a dial to a specified setting.

In case you are wondering; "binaural" is not stereo but can actually be better than stereo. The problem is finding recordings actually done in "binaural." We offer this quote on the subject;

It is important to recognize the difference between a stereophonic system and a binaural system. The former system uses loudspeakers but requires an infinite number of channels for perfect reproduction. The latter requires only two channels for perfect reproduction but involves the use of a pair of head receivers [drivers] held tightly to the ears for each listener. All listeners with such a system can be given the illusion of sitting in the best seat in the concert hall. Harvey Fletcher; The SMPTE Journal Vol. 61, September 1953.

Be that as it may, there is still only one "out" on the GDP50 and we don't have the amp that went with it. Furthermore there is no headphone jack. We have to use this unit as run through the Bogen (integrated amp) for listening purposes, but straight to soundcard for transfers.

Aside from the need to rectify hum this compensation amplifier really is a blast to use. The results a of couple of 78s we transfered to CD with this unit in addition to a Technics SP10 MKII turntable, an SME 3009 tonearm housing a Shure M78s cartridge still stands up next to the professional jobs I have heard of the same discs issued by the Melodie Classics label.
