OK, here is the pinout for the modules that were/are sent with the mugs. AND no comments about procrastination, it is being done in the same calendar year, so I met schedule
there are 12 pins per side, and the sides are identical, so I will only give pinouts for one side.
I will call pin 1, the end pin, in the group of 2
12 3456789 10,11,12
pin 1 is the output side of the feedback network for the output stage. it is not connected internally to the output. you must do so outside the module.
pin 2 this is the output of the module. It should be tied to pin 1, or you can increase the gain by putting a resistor between pin 1 and pin 2.
pin 3 this is the input to the output stage.
pin 4 not connected, i think (some of you may have odd modules that had an unused option here)
pin 5 output of an internal summing stage resistively buffered
pin 6 +15 V
pin 7 ground (if such a thing exists)
pin 8 - 15 volts
pin 9 output of part of the shaping circuitry for the crossfeed. not resistively buffered , This same output is one of the summed outputs on pin 5
pin 10 output of a shaping stage. not resistively buffered
pin 11 input to the shaping stage whose output is pin 9,
pin 12 input to a gain stage (A=2) that is the other input to the summing stage whose ouput is pin 5 ALSO, the input for the shaping stage that is the OTHER sides pin 10 output.
power and ground have to be supplied to both sides of the module.
Not everyone has the same module, and I have no idea which one anyone has.
Easiest way to run the modules hook up power and ground to both sides, input is pin 12. short pins 1 and 2 together, and use as output. input to volume control pot is from pin 5, and the wiper to pin 3.
There are several ways to hook up the modules. have fun
and for those of you who want more information. my first post was
have fun, and have a great new year And thank you for the great letters.
