I'm selling my 2-year-old Woo WA6 with an upgraded Sophia Electric Rectifier and 6GL7/6EM7 upgraded tubes. Retail (with upgrades) is $1050. I have loved this amp, it performs marvelously, and the only reason I am selling it is to move to a solid-state AURALiC Taurus for my new LCD-3. It is in perfect condition, can work with 110V or 220 V and has its integrated power supply. Ships with original foam, original tubes, upgraded tubes, amp, and power cable (not included by Woo).
