Product Condition Grades
Below is a general description of what the criteria is for our product condition grades. These are generalizations that are intended to give you an idea of the condition of the product at a quick glance. Because different parts degrade at different rates, there are variances in what the letters represent, please see the products description for details about the condition of any particular product.
A = Excellent / Above Average
B = Average / Some flaws / Good to Excellent Driver Quality
C = Obvious flaws / Poor to Average Driver Quality
D, E, F = Worse, Worser, Worsest
Good used PCB that has no burns, corrosion or separating areas. The red PCB (printed circuit board) was used in the latter part of 1969 (from 2/17/69 on) and all of 1970. In 1969 if you had a white plug connected to the PCB it used a red PCB, if you had a black plug the blue PCB was used.
