The TC-778 combines the proven low noise discrete RIAA design found in the TC-750 with the ability to select equalization much more appropriate for playing and recording 78rpm records.  Dedicated rear input jacks accomodate a separate 78 table; or the same input can be used for both RIAA and 78 (for those of you who have one table capable of playing all record speeds). Simply set the rear panel switch to the position which suits your situation.
