All of my readings were within 10% except the following.


TS   Expected     Actual
2        71K            84.3K
4        60K            73.8K
12      60K            74.1K
14      71K            84.6K


 Please advise on how I should proceed.

EDIT:  I have now reflowed ever terminal strip.  No change.

THANKS!!

OK, I looked forward thru the form and saw where another got similar readings and that it was OK. 

I proceeded to check the resistance for the sockets. I had some readings there that were also high which I also assume are good.  However pin 4 on scokets A, B, and C all return a value of .621K

I think this is a problem.  Can someone in the know please advise.

OK,

I re-read this post:
http://bottlehead.com/smf/index.php?topic=8858.0

He had the same reading so I proceeded to the Voltage Check.

Everything was within a few volts except OB on one board (100vdc expected)  I got 45.6vdc

Please advise.

I just re-flowed all of the connections on the card in question.  No change.
