Isn't it significant to users of variable resistances that the NATIONAL-LYNCH Power Amplifier and B eliminator — the quality job of the year — is equipped with Clarostat.
Clarostat, the greatest variable resistor, is standard equipment not only in the apparatus of the National Co., but in the products of 90% of the B eliminator manufacturers of the country.

A Special TOBE B-BLOCK with hi'Voltage condensers was chosen for use in the NATIONAL POWER AMPLIFIER. TOBE Buffer Condensers are used in the B'Supply Units also, and each audio coupling condenser is a 0.1 Mfd. TOBE. The NATIONAL Tone-Filter uses a big TOBE, too.
TOBE Condensers are used because they are good condensers. Ask your dealer for TOBES and TOBE B-BLOCKS.

Chosen by EXPERTS
JAMES MILLEN, Lawrence M. Cockaday, Gerald M. Best, and many other eminent radio designers use the Lynch Metallized Resistor in their experimental circuits and receivers. These men know radio; they have laboratory and testing equipment with which quickly to make accurate comparisons. There could be no better proof of the true merit of the Lynch Metallized Resistor than the endorsement of these experts.
Comprising a concentrated metallized deposit one-thousandth of an inch thick upon a rigid core, sealed forever within a glass tube, the Lynch Metallized Resistor gives conductive, non-arcing resistance that remains silent, accurate!
Guaranteed accuracy — 10f c; in production they average 5%. .25; 5; 1; 2; 3; 4; 5; 6; 7; 8; 9; 10 Meg., 50c. .025; .09; .1 Meg., 75c. Single mounting 35c; Double, 50c. If your dealer cannot supply you, send stamps, check, or money order. We ship postpaid same day order is received.
