Errata

Berlow is a list of issues that have come up by our builders.

There are two caps marked C48 on board with different values. One is between the phone and paddle jack and the other is just below U9. Note that the cap between the phone and paddle jack should be C30 (.01 UFD)
The color coding in the instructions for R6 and R7 are incorrect and should be orange orange yellow instead of red red orange.
The 4.7pF cap may have been replaced by a green 5pF cap with a black dot. Either will work.
Some of the electrolytic caps call for 16V parts. 25V parts may have been shipped, again either will work.
In the section on the Low Pass Filters it calls for a 33 pfd cap to be installed. This should be a 22 pfd.
In the Group 2 assembly, C26 .1 ufd should be installed with C25 and C28
