A Modular Hybrid Amp System

Tubes or transistors? Whatever your prejudices, this article may make you change your mind about how you view hybrid designs. audioXpress featured this modular hybrid amplifier project in February 2001, which was referenced multiple times by other authors in many subsequent projects. The project features a shunted regulated push-pull (SRPP) stage design, using the ECC82/12AU7 tube combination, followed by a power stage, using two to eight complementary power MOSFETs in parallel.

A Hybrid Valve MOSFET SE Amp - Complete Project

Published in two separate parts in audioXpress October and November 2007, this hybrid amp design is a detailed and interesting project, frequently referenced by other DIY audio enthusiasts. We thought it was time to make it available online in its entirety, in the best possible quality. The article discusses the unity-gain, single-ended MOSFET output stage, the valve voltage amplification stage and wraps up with the power supplies, printed circuit boards, and construction.

IFA Berlin 2017 with More Exhibitors and More Innovations Than Ever Before

The International Funkausstellung (or The International Consumer Electronics Show) in Berlin is probably the most important annual event for the consumer electronics industry, introducing new products in time for the most important season of the year for sales. IFA 2016 featured more than 1,800 exhibitors and attracted 240,000 visitors, with the majority of trade visitors coming from outside Germany. The 2016 floor space was already the larger in the show’s history. Expect the 2017 edition to be even larger!...

Amplifier War and Peace - An Hybrid Amp

Amplifier War and Peace - An Hybrid Amp

Simon Brown rethinks what he needs as the amp that will be the centerpiece in his own audio system and perfects a previous design with a true hybrid design. As he writes, "This amp is a “hybrid” in many ways. There is the obvious way in which it uses both valves and MOSFETs. But it’s also a hybrid in its use of enriched Class A/B, which means it is running Class A up to a few watts. This is deliberate." Read the complete project now. This article was originally published in audioXpress, March 2007.

A New Dual Discrete Op-Amp for Audio Products from Orange Amplification

Once in a while, British guitar amp specialists - increasingly turning also into a lifestyle brand - surprise the industry with some unusual products. We've seen Orange introducing headphones, the VT1000 valve/tube tester and even an automatic bias adjustment kit, the DIVO OV4. But now, Orange truly surprised us, with the introduction of its new Dual Discrete Op-Amp, which has been specifically designed for audio use. Orange simply says, "it is one of the most musically sounding of its kind on the market today."
