FYI, Around the database you will often see us describe the condition of units on a scale of 1-10. #10 would mean the product is new from one of our suppliers, such as Behringer, Audio Technica, etc. #9 means the product is in perfect condition but is used, #8 implies there are some minor cosmetic scratches but unit is mechanically perfect, and so on and so forth.

Burwin TNE-7000
# 27814
Click and Pop eliminator, excellent condition, modified - call for details

The TNE is rackmount and in like new condition, but I only sell the Audio proz modified version. (This is a highly in demand piece that usually has a waiting list) This mod makes the unit work remarkably better. The same is with the 1201A, which is in a slightly worn condition, but certainly very acceptable. This unit also has a modification. See our listing # 60892I was the chief line tech and production assistant at Burwin research and even though my modification is simple and clever, it took a year to design. I myself was desperate for a better, wider applicable performance. The unit works better with many phono preamp cartridge combinations. I do prefer Stanton and Audio Technica cartridges because these guarantee honest bandwidth and correct stereo separation which is critical to best nick pop elimination. The Stanton 680 or 681EEE or AT 311 EP or 440ML is excellent. Indeed the ART phono preamp with proper cartridge loading switches and level control will optimize the TNE performance. I am on the side of laboratory standard ideals and not audio-“phoolish”, intentionally off RIAA standard preamp designs, which can be sometimes interesting sounding, but is usually just strange equalization tricks to impress the consumer. In my opinion its best to have an out board equalization to fix the many and varied equalization “opinions” existing on the stereo-mix of the record.

SAE 5000A
# 55950
Phonograph nick and pop reducer. Does not have preamp. INR SYS INVERT/DEFEAT, TAPE MONITOR, SENSITIVITY FADER. AP mod done to improve control calibrating and sensing and filtering the pop or click. Also board has been ruggedized with solder and better caps in power supply. Black brushed aluminum face with wood sides. Minor modification to sensitivity control to lessen audible blanking of audio. Fully serviced, low hours use. 9 + condition. It works good but TNE or Burwen 7000 is a superior design and with my mods it's as good or better than any computer attempt. I worked with Burwen and have upgraded a superior TNE. I am a little famous for this as well as APT products.

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.
