Burwen 1201A

Audio Proz Inv #: 25981

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.

Burwen KLH TNE 7000

Audio Proz Inv #: 51201

Latest version. With AP Rev4 modifications, excellent performance! See modifications page for more details. Excellent #9 cosmetic condition. Special capacitors replacement is of no importance to improve performance of sound. The mod I do will allow use of a different 'delay, all pass; op amp and also will clearly improve audio quality during tick removal, functions and fidelity. But I don't give out that clever intellectual property, I only have engineering blue print as such it is too large to copy. call direct or provide # I will explain the details. I've modified 100+ of these and everyone now agrees with my opinion. By the way almost all of these capacitors you see are for power supply 'by pass' and in fact are not in the audio path. As the unit ages correct calibration of de click circuit is most important concern. My modification reduces the need for future recalibration.

Burwin TNE-7000

Audio Proz Inv #: 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. I 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. The TNE is $380 and the 1201A is $240.
