Write Up: Hi, I am a Chartered Electrical Engineer and have been building, designing and repairing all types of amps (mainly valve) for +45 years. Based in North Notts. I have now decided to concentrate solely on valve amplification, whether that be for HiFi or guitar. Please don’t hesitate to drop me a line using the above email address or via the contact page on my website if you need any help. My basic principle when repairing customers’ equipment is to leave as much original as possible and only change components when absolutely necessary or where there is a known modification that enhances performance, I don’t subscribe to the ‘shotgun’ method of changing things until it works – a bit of theory and experience goes a long way! Many Thanks, Dave.

Write Up: Greetings! I have 45 years experience in electronic design, manufacturing and repair. I started off at the BBC and then formed my own design company, Racom Ltd. I am now self-employed having sold out my interest in Racom many years ago. I work from a large workshop attached to my house. My work is 95% valve guitar amplifiers, the older the better! I do a lot of repairs each year. I really enjoy renovating the older amplifiers. I can also undertake design work if you have ‘a project’! Drop me an email on the supplied address.
