The Harpo

Built for Richard Pappik of Element of Crime

This is yet another of the portable suitcase tube amps– this time with reverb and delay.  Ricci wanted an amp to use with his harmonica that was small, looked good, and was loud enough for gigs.  The circuit uses an ECL82/6BM8 in single end format and there’s an active mixing stage for the three signals– straight, delay and reverb for a clean sound at higher levels.  The amp was also tested with an electric piano and is perfect for that application as well.
