Noise reduction module, accessory for 80-8 tape recorder, bag, manual, 16 RCA cables, no warranty card. Known to be in good condition. This unit is priced on request depending on service required. $250 (Tested appears to work, minimal repair, clean up time is spent) - $400+ range (Full restoration everything repaired, all relays cleaned (there are 16 of them!!) tested, calibrated, etc.) These are 30 years old, it is almost a requirement to really perfect. Once serviced correctly these are very reliable and great performing machines. We also do a modification in the circuit which reduces the circuit noise another 4 to 6 db and also reduces the crosstalk, simulsync, playback at high frequency by almost 10 db. A significant improvement. $160 for the modification.
