Matt reports: This is quickly becoming my favorite amp. The 6CY7 stereo amp uses a 6CA4 tube rectified power supply with excellent channel separation. This amplifier did a little better than this having a -3dB bandwidth from about 46Hz to about 30kHz. The Edcor XSE output transformers are rated from 70Hz to 18kHz.
