While browsing the Valve Wizard website I discovered that Merlin Blencowe had written and self-published two books called “Designing Tube Preamps for Guitar and Bass” and “Designing Power Supplies for Tube Amplifiers”. I have long been a fan of Merlin’s clear and informative style of presentation so I decided to buy both and I’m glad I did.
From my experience it is unusual to find as much useful information in a modern book on Valve/Tube Electronics. I have only had time to read sections of the book about Preamps so far but Kevin O’Connor’s “The Ultimate Tone” is the only other book I have read which has provided so much food for thought. Merlin’s books explain the fundamentals of circuit design so do not make for easy reading but Merlin takes a practical approach which makes the subject easier to digest.
I bought both books from Amazon in the UK. Both books are still available despite Merlin’s warning that the volume on Power Supplies is now out of print. At just over £40 including postage for both books, I think they offer exceptional value for money.
