We are very careful to test the equipment before it’s packed and then to double box the machine with added protection when needed for front panels, etc. We are not amateurs or an ebay store; we know these machines very well and know what it takes to get them to you safely. We use USPS priority internationally which seems to be the cheapest. If you prefer another carrier (you should know who delivers to your area reliably) please let us know.

Noise Reduction, 2 rack space, Modified by AP to reduce hiss very carefully without excessive high frequency loss. Works well on tape and FM signal, 4136 opamp gives slight tubaphonic veiled sound. A somewhat archaic device but still usable as a substitute Dolby decoder or to warm up the audio character of excessively bright recordings.

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.
