An interview with Kevin Hayes Of VAC. The KT88 and the 300b tube are some of the most popular options for HiFi amplification. But what are the differences and why do some amp designers choose one over the other? Kevin explains the situation and also discusses Class A, if amplifiers "warm up", and if tubes sound better in the pre amp or power amp. A very educational and inspirational interview with a tube designer that has been in the business for over 35 years.
