EDIT : Solved - User Error
Just added the Speedball to my Crack and did the resistance Check. The following didn't match the manual:
T7- 1.8M and climbing
T9- 2.2M and climbing
T13- 1.4M (this read high on the original build, Paul confirmed it was ok)
B3- 1.9M and climbing
B6- 1.9M and climbing
Since B3 is connected to T7 and then to the output cap (same for B6 & T9) could those readings be caused by residual charge in the output caps?
