-What is the 470pF cap for?
we have added a 470pf cap to the kit. It is not in the assembly manual but it IS marked on the board. It goes in the middle of the upper half of the board next to a vertical block of .1uF caps. This is to keep high frequency oscillation from occurring in the output mixer.
-How do I read the value of the potentiometer?
As of March 2013 we are using a different distributor for potentiometers. The new pots have a blue body and are higher quality than old green bodied ones. Unfortunately they are a little harder to read. The value of the potentiometer is printed on the bottom using the following code.
10k = B103
100k = B104
500k = B504
This is actually a very common way of marking components. The first letter indicates the taper of the pot. In this case it is a “B” which means the pot is linear taper. The 1st two digits stand for the value of the pot. The 3rd digit is the number of zeros which follow the first 2 digits. For instance “103” means “10” followed by 3 zeros, which is “10,000”. This pot is 10k ohms.
