OTHER COMMUNICATORS FOR LOW POWER INDUSTRIAL AND GROUND-TO-AIR APPLICATIONS^. Me^jU FREED COMPONENTS /o^ HI-FIDELITY AMPLIFIERPROVIDE IMPROVED PERFORMANCE This Freed circuit incorporates several changesfrom the original Williamson circuit to provide op-timum performance at high and low frequency ex-tremes. It is rated at 10 watts with triode connectedoutput tubes. However, by connecting the screengrids of these tubes to taps provided on the FreedKA-10 output transformer, it is possible to doublethe power output for a given distortion percentage. Recommended power supply is choke-input typewith a two-section L-C filter to maintain output and to improve filtering to the voltageamplifiers. Other high quality Freed components Include minia-ture audio transformers, magnetic amplifiers, toroidalinductors, subminiature encapsulated pulse trans-formers, precision filters and a complete line ofprecision laboratory test instruments. Complete cata-logs are available to engineers requesting same onfirm letterheads.
