Installing the rectifier tube: Note: avoid oil or smudge on the tube glass, clean hands before installation. 1. Find the correct tube for the socket. There is a label below each tube socket that indicates a standard tube for the amplifier. For example, a 5U4G or a compatible tube should install on the “5U4G” labeling socket. You MUST use the compatible tube or serious damage may occur to the amplifier. See Compatible Tubes section for all the approved direct substitute tubes. 2.
. 4. Check installation. The tube pins should be inserted fully into the tube socket receptacles. Installing the driver/power tube: Opening gap indication on the bottom of the tube Align the tube to the tube socket Insert the tube perpendicularly to the tube socket Use both hands if the tube is hard to install Selecting AC voltage: WARNING: failure to select the correct voltage will result in damage of the amp. Switch to label “115” for AC100 to 125V voltage. tm ©2011 WOO AUDIO Inc.
Installing the power cord: Plug the power cord into the AC inlet. See ② in the below diagram. The AC inlet socket is a standard IEC type. You will need to obtain the correct type for your region. U.K. European U.S.
Operation DO NOT o Turn on the amp before properly installing ALL tubes. o Use tubes that are not approved by Woo Audio. o Turn on the equipment without checking the correct AC voltage setting. o Remove any tubes or the DC cord while the amp is operating o Touch tubes (extremely hot) after warm-up. o Leave the amps running unattended. To use the amps safely, please allow it to cool down for every 8 hours of continuous play time.
Turning the amplifier on: 1. Turn the volume knob to the lowest position. 2. Insert a headphone into either HIGH or LOW impedance output. 3.

Reviews “For a roughly $1,600 total investment (including Sennheiser HD600s, upgrade cable, Sophia 274B, and some spare tubes), we were getting sound and emotion equivalent to spending $90,000 on an Ongaku along with the kind of speakers you'd normally pair it with.” – GalibierDesign “If you want valves through and through, with admirable performance to boot, this system's well worth considering.” – Crave “The WA6SE packs a punch. It just screams power.
