6V6 12AX7 Stereo Amp

Little stereo vacuum tube amplifier built for a friend who wanted a tube stereo at minimal cost. It used mainly parts on hand, including a vintage radio power transformer, vintage tube sockets, and NOS 5 watt Zenith audio output transformers made for 6V6 single-ended output stages. The driver tube is 12AX7 and the tube rectifier is 5Y3G. Output tubes are old Zenith 6V6G tubes, the tall ones that look prettier than the GT style. The tube amp delivers great sound with an MP3 player as the audio source.
