Dynaco PAT-5 Stereo Preamplifier (1974 MSRP  $239 Kit, $399 Built)

Dyna's replacement for the venerable PAT-4, adding such niceties as a high-power switchable outlet, speaker selector and terminals, dual tape monitors, an external "processor loop" intended for EQs or other signal modifiers, and an op-amp high-level stage.

This replaced the NS LM301 opamp in the PAT-5 preamp in 1977, opening the door for numerous audiophile mods including the highly acclaimed Frank Van Alstine and Walt Jung upgrades.
