This set suffered some shipping damage, resulting in its Restoration requiring more time than is typical.  Damage included destruction of its very rare 7DP4 picture tube and significant damage to the Tuner.  We were exceptionally fortunate to obtain a NOS replacement 7DP4 and to establish a working relationship with an excellent Machine Shop specializing in detailed miniature work.  We expect to complete this set's Restoration soon.  We have reached the point of the set's producing recognizable Picture and Sound, and are currently working toward further improvement of overall performance.  The 621TS is an exceptionally rare and valuable example of Postwar TV, and we intend to perform the requested Heirloom Grade Restoration to the high standards of which this model is worthy.


Picture quality is still substandard in this photo, but steadily improving toward optimum picture resolution.  We suspect that this set may have been stored in a somewhat hostile environment at some time, since we have encountered a far greater incidence of carbon resistor failures (excessive drift outside rated tolerance, excessive noise, etc.) than average.
