Bang & Olufsen Resurrects Beogram 4000c Turntable

We know vinyl is trending and that turntable options are expanding in every price segment. But after the return of some "ghosts" from the distant past (in electronics, basically everything before the eighties), Bang & Olufsen now tops the list of "resurrections" with the rebirth of its Beogram 4000c Recreated Limited Edition. Bang & Olufsen says it's the return of an icon, "reimagined for contemporary homes," and the start of a new approach for the Danish brand.

Borbely RIAA Preamp With Tubes - A Project Remembered and Revisited

This approach to RIAA equalization results in a high-quality phono preamp featuring the high-transconductance 5842 tubes. The author adapts Erno Borbely's project of a transistorized phono preamp with a vacuum tube implementation. These articles were originally published in audioXpress, October 2003 and January 2010. For this repost, we decided to merge the two articles in one single page.

Disc Recording Equalization Demystified

This article explains the methods of cutting disc records, the characteristics of magnetic phono cartridges, and how their combined response determines the required playback equalization. The article is based on a paper the author presented at the May 1996 conference of the Association for Recorded Sound Collections (ARSC) in Kansas City, and was first published in the Fall 1996 issue of the ARSC Journal. Later, the article was featured as part of "The LP Is Back!" compilation book published in 1999 by The Audio Amateur company.

Getting the Most from THAT’s Balanced Line Drivers and Receivers

Getting the Most from THAT’s Balanced Line Drivers and Receivers

I completed the design and construction of an archival phono preamplifier, which provides variable equalization along with several other operational necessities for playing vintage records (78-rpm discs, pre-RIAA LPs, lacquer transcription discs, and so on). When it came to selecting topologies for the balanced inputs and outputs, I ruled out transformers due to high cost, physical bulk, and weight. The most practical choice, in terms of size and cost, are the balanced line driver and receiver ICs made by THAT Corporation. This article was originally published in audioXpress, June 2010

You Can DIY! Build an External Phono Preamplifier

You Can DIY! Build an External Phono Preamplifier

Many of today’s receivers and preamplifier processors do not have phonograph inputs, so anyone with a vinyl collection will need an external phono preamplifier. Bill Christie decided to build one using a TI high-performance op-amp, since the data sheet already included the schematic for a phono preamplifier. This article was originally published in audioXpress, July 2013.
