New build wrong resistance question

[tywoods]

Hey guys,

I just built a crack to specs 220v. Checking the resistance, I get .41K instead of 2.9K. Everything else seems ok

7. .41
9. .41

B3 .41
B6 .41

Anyone know my mistake? Could it be I didn't twist the ends of the 10w 3K resisters well enough? It sort of came undone, but I filled it with solder anyway. I'm wondering how to redo it, and if that is my issue.

Thanks

That's an odd reading!  Can you upload a couple photos of the octal socket area?

[tywoods]

Paul,

I really appreciate the attention. This was my first time doing something like this. I tried to prioritize making a good connection over making it look good. Excuse the mess. Here are some photos.

Thanks again

That solder joint at 3U won't do.  Can you get the leads through the top hole?

[tywoods]

Thank you for the support Paul!

I used a solder wick to remove the solder, twisted the pair real nice put it through the hole and laid some solder over it. I also re-did B5. Not much change, I am reading between .39 -.43 on all 4.  Typically its a constant .40

I'm suppose to test with the black on 12U and then B3 for example with the red right?

Anything else you might see? Could you please tell me which connections these 4 tests rely on and maybe I can just redo them all?

Here are some more/new photos. Thank you sooo much

Here are a couple of my tester. Same connections tested, but different settings on the tester, not 100% which is the right one to use.

If you put it on 20K, what readings do you get at 7/9?

[tywoods]

.40 for both

its 0 at 3U and .40 on 7U and 9U.

[Paul Birkeland]

Try carefully removing the 100uF cap between 6 and 7, then recheck and see if that changes the reading.

Paul,

Thank you for your continued support.

I removed the blue 100u capacitor and no change. .40 on 7

I then removed both blue capacitors and got no change.

I then removed the solder from the entire 7 and 9 leads and tested the leads coming straight out of the 10W 3k resistors. and its .40 for both.

I'm like

If you measure one of the resistors itself, what do you get?  This may just be a meter issue. 

[tywoods]

lol it is a cheap meter I bought in a 3rd world country.

Right out of the resistor (The opposite of the twisted side) both of them are reading .40.

Try another meter?

[Paul Birkeland]

I'd go ahead and just move on to voltages.

[tywoods]

Its ALIVE! OMGOMGOMGOMG   

Thank you sir. Much appreciated!

If the multimeter was the problem, it doesn't cost too terribly much to get a relatively alright one. I bought this one because my old one wasn't sensitive enough to measure voltage in a way that was meaningful for troubleshooting. It works pretty well!
