A must have book for vacuum tube amplifier fans!, November 15, 2000
This review is from: Mullard Tube Circuits for Audio Amplifiers (Paperback)
This is a book which is not only useful for its historical value but also for the constructional articles inside. Many of the circuits are very similar to those found in classic valve amp brands like Leak, Quad, Radford, etc. As it is a reprint of an old book some of the components may not be easily available, especially output transformers, switches and capacitors. Theoretical information is kept to a minimum and is very useful. This is a book for constructors who really want to build their own amp. The is an excellent stereo preamp design and 20, 10 and 3 Watt mono amp designs. Designs for 7 and 3 Watt stereo preamps are also included. There are chapters on sources of distortion, hi fidelity amplification, construction and assembly.

The 1958 State of the Art in Home Audio, May 6, 2004
This review is from: Mullard Tube Circuits for Audio Amplifiers (Paperback)
If you wish to build vintage audio equipment, this book fills the bill nicely. The state of the art in 1958 was surprisingly good, the builder will bear in mind that the book is written for English reader/builders whose smaller homes and penchant for more efficient speakers even then placed emphasis on smaller amplifiers than Americans tended to prefer. On the other hand, it's precisely the little EL84-tubed amplifiers today's vintage-tweako element seems to prefer, and if you are unhappy with your project you can always recycle it into a guitar amplifier! The projects in this book can be built very cheaply today, the only big expense being the output transformers, and even these are not terribly costly. I believe the intermediate hobbyist will do much better to build from this book with modern components rather than throwing good money into forty-year-old mediocre products such as those now bringing large sums on eBay-with the exception of Mac and Marantz and some specialty or industrial/professional products, most fifties and sixties hi-fi units were actually not very good.

Classic Never Goes Out of Style, July 8, 2007
This review is from: Mullard Tube Circuits for Audio Amplifiers (Paperback)
This is an interesting read, of historical value and a pretty good guide to some basic valve amplification circuits. The power amps described are all push/pull so if you're looking for a class-A single-ended design, this isn't your source. Still, it's worth keeping in your library. At sixty dollars it's a bit pricey but at the cover price of $16.95 would be quite reasonable if it were still available. Oh wait. It is still available from Parts Express and it's even discounted so now you don't have to agonize over the expense. I'm still kicking myself over that one.
