How to adjisut the output power (WATT)<br />
1. Delete R67 and R68 ->6dB UP<br />
2. Delete R74 and R78 ->11dB UP<br />
3. Delete R72 and R77 ->16dB UP<br />
4. Delete R71 and R76 ->21dB UP<br />
5. Delete R12 and R75 ->26dB UP<br />
Please try to increase the power by above order(1-5).<br />
Even doing above modification ,If POWER is not go<br />
to correct wattage, please exchange the TUBE itself.<br />
