A little more yellowing on this one and one small spot on the proto board socket... No serious problem but a spot, most likely from a hot resistor...... GLOBAL SPECIALITES PROTOBOARD PB-503 Ideal for analog, digital and microprocessor circuits Includes built-in Function Generator with continuously variable waveforms Triple output power supply for a variety of DC voltage levels Two Digital Pulsers for logic test circuits High & low buffered logic indicators 8 channel logic monitor Audio experimentation speaker NOTE:: There are several “models” of the PB-503… Many do not have the power supply built in as this one does. Variable plus and minus 0 – 18 volts as well as plus 5 volts. There is a strap rivited to the side which I assume is/was to hold the cord. Otherwise there is some discoloration of the plastic from the original white to yellow. This is a used item that has been tested and found to work, has output and signals can be modified… THIS AUCTION IS FINAL…. NO RETURNS. If you have been looking for something like this, here is a good chance to get it. Thanks for looking. I will contact auction winners after e-bay posts the results. Winner MUST respond within 3 days.
