"This is the only Wiard Model 311 Option S Controller that was or ever will be manufactured.

(I once owned a Serge Series 76 and built this controller to use with it during the time I manufactured the Wiard 300 Series. The Serge 76 went to a better home before this was finished, and so the controller became redundant.)

Features:
2 x 0-5V filtered precision voltage sources (joystick controlled), op-amp buffered.
Bakelite vintage style volt meter from railroad supply company (30KOhm)
2 x 0-5V trigger outputs with indicator LEDs (de-bounced pushbutton activated)
1 x ground banana jack
4 x multiples with banana, 3.5mm, RCA, and 1/4"
Runs on either +/-12V or +/-15V
2U high, 19"
Hand built and silk-screened by Grant Richter"
