Home > Vacuum tubes by type > Power tubes > KT88 Types These KT88 tube descriptions now include the results of the listening test we performed with Roman Klun, a recording engineer and producer who has worked with artists such as Sarah McLachlan and the Boomers. He listened to all of our KT88 tubes and 6550 tubes with his own reference recording and gave us his observations. KT88, KT90, and KT100 tubes are interchangeable types. The amplifiers we use for our listening tests are from Quicksilver Audio. These are great amps since they allow us to quickly compare many different types of tubes without having to re-bias. The speakers we are using are Vandersteen 2Ce's.
