If the circulator load has failed, the Final or<br /> Driver PA module may have been damaged. If the circulator load<br /> needs replacing, the PA deck should be retested to insure proper<br /> performance. &lt;/p&gt;<br /> <br /> &lt;p&gt;Power Amplifier Kits Involved: &lt;/p&gt;<br /> <br /> &lt;p&gt;TLD-3110A QUANTAR-- 25 WATT--VHF TLD-3101A QUANTAR--125<br /> WATT--VHF TLD-3102A QUANTAR--125 WATT--VHF TLF-1930A QUANTAR--100<br /> WATT--800 MHZ TLF-1800A QUANTAR--100 WATT--900 MHZ &lt;/p&gt;<br /> <br /> &lt;p&gt;NOTE: This is an Informational Bulletin only.
