In The C70 KT-88 Vacuum Tube Stereo Amplifier, Bob Cordell shows he is equally well versed in tube technology as he is in solid state design. This amplifier uses solid state devices in the regulated power supplies and cathode current sources, to produce a 35wpc amplifier that embodies the best of both worlds. Specs are impeccable, and if reactions at Rocky Mountain Audio Fest sessions are anything to go by, so is musical performance. Bob also identified a modern output transformer for this design so it can also be used for a great construction project.
