control at lowest cost. Typical of Dynakit design<br />
and engineering effectiveness, this latest advance<br />
adds stereo control to two preamps without<br />
noise and distortion. Versatility is assured<br />
in this unit with level, balance, loudness. channel<br />
reverse and dual tape monitor controls. Handsomely<br />
styled, the new Dynakit Stereo Control<br />
and Preamplifier combination are a bargain buy<br />
for anyone building his own stereo system.<br />

Code *: ER denotes exact replacement. NR denotes nearest replacement. Socket and /or<br />
wiring changes may be involved here, or slightly different electrical characteristics and<br />
ratings may have to be considered in some circuits.<br />
NOTE: The increasing sale of imported receivers and audio equipment has resulted in the<br />
problem of obtaining replacements for some of the unfamiliar tubes used. This list, reprinted<br />
through the courtesy of Sylvania Electric Products Inc., 1740 Broadway, New York 19, N. Y.,<br />
is believed to be accurate. However, neither Sylvania nor ELECTRONICS WORLD assumes responsibility<br />
in case of error. The complete Sylvania list also includes foreign -made replacements,<br />
available in this country, for other foreign -made tubes that are not generally marketed<br />
here. These additional listings will appear in a forthcoming issue.<br />
