Please check back for more stock at a later date!

This 770x Preamp set is fully functional and in great condition.  This set of preamps have been custom modified to function as standalone preamps with additional XLR inputs & a 48v phantom power source installed as well.

The Roberts 770x is a 1/4" reel to reel multitrack tape recorder from the 60's with a 2 channel preamp section for the recording inputs.  These preamps have become desirable in their own right & can occasionally be found in their presented condition, seperated from actual tape machine & modified for use as general purpose preamps.
