I like the Woo line of tube headphone amps so much I'm moving up the line to the WA-6SE. Unfortunately, that means I need to sell my wonderful Woo WA6. This amp is in excellent condition and comes with cool upgrades/extras. Along with the Sophia Electric Princess 274B/n tube I've also added a pair of NOS Raytheon 6EW7 tubes. Additionally, I replaced the cheap Chinese fuse with a Hi-Fi Tuning fuse. All told this is a great little amp at a great price. SOLD I do accept PayPal but the Buyer must pay their fees.
