In the Alignment and Installation section of the Rev E manual I may have a
problem with the resistance tests in the table on page 43.
J3 resistance to ground, after about 20 seconds is okay (6.6K which is >
5K). However, Q1 and Q2 collector to ground start at about 30K but decrease
over a similar time to only about 8K (significantly less than the required
10K).
Also the final test, D13 cathode to ground increases to about 9.4K after a
similar time (which is still less than the require 10K).
Any thoughts on what might be wrong or are these reading okay to move
forward to the powered test? I'd rather not fry things before I even get
started! Thanks for any help.
David, K2MUN
