Troubleshooting help - bad resistance measurements [resolved]

[notphilip]

Hi all,

I just finished my first BHC build, but it looks like I have some weird resistances popping up.

Any ideas on what to check for first?

Here are some pics: http: //imgur.com/a/tpOml
Below are my measurements:
Terminal   Target           Measure
1              *                   Starts at 20Mohm and slowly decreases
2              *                   Starts at 20Mohm and slowly decreases
3              0                   0
4              *                   Starts at 10MOhm and slowly decreases
5              *                   Starts at 8MOhm and slowly decreases
6              2.4KOhm   2.49KOhm
7              2.9KOhm   37MOhm and slowly climbs
8              0                   35MOhm and slowly decreases
9              2.9KOhm   37MOhm and slowly climbs
10              2.4KOhm   2.49 Kohm
12              0                   0
13              * climb towards 270KOhm   6MOhm and decreasing
14              0                   0
20              0                   0
22              0                   0
B3              2.9KOhm   35MOhm
B6              2.9KOhm   35MOhm
RCA ground red   0           0
RCA center pin red   90-100KOhm   110.1KOhm
RCA center pin black   90-100KOhm   38MOhm
RCA ground black   0   0

7              2.9KOhm   37MOhm and slowly climbs
9              2.9KOhm   37MOhm and slowly climbs
RCA center pin black   90-100KOhm   38MOhm

These and their connections to the B socket are a little unusual, and the RCA jack center pin is quite off.  Do you have the jumper between the pair of lugs on the pot where the black wires connect?

Can you double check that you have a 3K/10W resistor between terminal 3 and 7, as well as one between terminal 3 and 9?

Thanks for the suggestions!

It turned out to be a bad solder joint at terminal 13.
 Once I fixed that, everything else downstream measured correctly.
Voltage checks went well too and it finally works! It sounds awesome
