Analog Audio Repair

This was a fun project that involved removing some tape deck electronics and modding the remaining circuit into a tube mic preamp with DI.  As you can see, several of the tubes are not needed when using this as a preamp.  A whole bunch of other parts came out too which cleaned up the crowded underside of the chassis a good bit.  The headphone jack is now the DI input and the Input/Tape switch selects either the mic or DI.  The Line Rec Level pot is now the DI level control and an XLR output jack has been added on the side.
