 Only the bare PCB is sold here. No component is supplied. You have to assemble the test bench by following the instructions below.
 To get an already assembled test bench, choose this product: Test Sys1


The are several areas on this test bench:
  • lamp outputs
  • coil outputs
  • sound outputs and audio amplifier
  • knocker output
  • 12V/5V power supply
Each lamp or coil output drive a LED. It gives a total of 43 LEDs!
  • 10mm green LEDs for coils
  • 5mm red LEDs for lamps
  • 5mm yellow or orange for sounds
Each LED is identified on the PCB, and labeled according to its function (lamps, coils, sound).

As an option, SOL6 SOL7 SOL8 and OUTHOLE coil outputs can draw a stronger current (0.4A) than a LED to get closer to the real driving condition of a coil (5A or more).

The 3 sound outputs (10 points, 100 points, 1000 points) activate 3 LEDs and 3 oscillators to recreate the basic sound board used on pinballs from Cleopatra to Pinball Pool.

The knocker output activates a buzzer.

The power supply is taken from the pinball 12V, with a diode in series to prevent polarity mistakes.

A complete kit with the components (except the bare pcb and the 3.96mm connectors) is available at www.gotronic.fr reference number 01104 :

The assembling is fairly easy. Gently bend U2 pins to insert it and bolt it to the PCB (use a 10mm bolt, a nut and a M3 grower washer).

X1 (loudspeaker) and X2 (buzzer) are polarized: the + pin goes to the + labelled hole on the PCB.

R1..4 and R19..22 are bigger resistors than the others because they allow a stronger current for the big 10mm LEDs. To insert R19..22 under A3J4, use:
  • the little pads that are linked to the big pads (top)
  • the little pads that are NOT linked to the big pads (bottom)
Be careful not to splash solder between the 2 series of little pads (bottom)!!

The 8 big pads underneath A3J4 are used to solder the big power resistors (which are not on the schematics). These 33ohms/3W resistors are to be soldered on the solder side as shown on the picture:

Important note: R19..22, Q1 and R51 are only designed for an intermittent use. Do not attemp to test OUTHOLE SOL6 SOL7 SOL8 and the sound outputs permanently or it'll get very hot!


The test bench can either be connected on the original driver board or on the PI-1/X4 board. All the connectors are aligned, so gently push to insert:

You can leave all the other connectors (A1J2 A1J3 to the displays and A1J6 A1J7 to the switches).

The 12V power supply is taken:
  • either on the PI-1/X4 screw connector

  • or on the big C1 capacitor on the original power supply board
