Heathkit
WA-P2
preamplifier
* 3 high-level inputs ea with level-trim control.
* Equalization for LP, RIAA, AES, 78.
* Separate bass and treble controls.
* Low-impedance cathode-follower output.
In planning the purchase of a really fine hi-fi system or improving a present one, the WA-P2 should receive your serious consideration. It has many fine features that will eventually be desired. Designed to operate with the Heathkit models W-3AM, W-4AM, W-5M and W-6M amplifiers, this control-center provides almost infinite combinations of equalization and compensation.
It features five switch-selected inputs, three high-level inputs for 0.1 Volts or higher at 0.5M Ohms input impedance and two low-level inputs, for 0.1 Volts or lower for magnetic phono pickup or microphone. Each input has its own level control to eliminate blasting or fading while switching through the various inputs, and will accommodate a record changer or player, tape recorder, AM-FM tuner, TV receiver, or microphone, etc.
Provision is also made for a tape recorder output that is not affected by the volume or tone controls so that the program material being recorded can be monitored without affecting the recording. A special hum control is provided for absolute minimum hum level. The low impedance cathode-follower output circuit allows complete installation flexibility, making the WA-P2 ideally suited for "remote" installations as output lead length is not critical.
The frequency response is within +/- 1.5 db from 15Hz to 35kHz.
Equalization is provided for records through separate turnover and rolloff switches for LP, RIAA, AES and early 78's. The turnover switch produces the rising low-frequency characteristics required for proper equalization since record manufacturers deliberately limit the low frequency intensity to avoid cutting into adjacent grooves. The rolloff control deemphasizes the high frequencies, removing much of the noise and scratch through four positions of 8, 12, 16 and 1 flat position.
Separate tone controls provide 18 db boost and 12 db cut at 50Hz on bass and 15 db boost and 20 db cut at 15kHz on treble. Power requirements for the WA-P2 are 6.3 Volts AC at 1 Amp, and 300 volts DC at 10 mA from the basic amplifier with which it is used.
Additional features include tube shielding, plastic sealed capacitors, smooth acting controls, good filtering, excellent decoupling, low hum and noise level, and an all-steel cabinet.
The WA-P2 has been carefully pre-engineered for you to insure specified high performance level. All components were especially selected for their high quality, and all values are clearly stamped to avoid mistakes. The construction manual contains complete step-by-step directions, with large pictorial diagrams that can be hung over the work area for easy reference. Successful construction is assured even for the beginner.
