Finished build. Resistance issues. Need help troubleshooting.
on:
December 24, 2020, 10:32:03 AM
Hi All,
I just completed my build and thought everything was fine. The tube glow test worked perfect. When I tried doing resistance checks I can only read the 0 ohm terminals everything else seems infinite. This is probably bad timing but hopefully someone can give some pointers on how to troubleshoot. I might reflow everything but I don't know what to do. I also probably would have powered it on if my readings didn't seem so messed up. I can also post pictures if needed.
Anyways here are what I measured:
Key:
0 is 0.
1 is infinite when it should be 0.
* is infinite
Terminal
1=0
2=*
3=*
4=*
5=1
6=*
7=*
8=0
9=0
10=*
11=*
12=1
13=*
14=0
15=0
16=*
17=*
18=*
19=1
20=*
21=*
22=0
23=1
24=*
25=*
26=1
27=*
30=~200 Ohms
31=~200 Ohms
32=~200 Ohms
33=*
34=*
35=*
36=1
(I might have measured these wrong. Not sure how to say what the measurement is)
H1= fluctuating between 0 and 1 depending where + probe is placed
H2= bouncing all over the place
H3= bouncing all over the place
H4= bouncing all over the place
H5=bouncing all over the place
H6=bouncing all over the place
H7=bouncing all over the place
H8=0
RCA Jacks
L center pin = 1 Ground tab =1
R center pin =94.8k Ground tab = 0
Hope you all have a wonderful Holiday!

Can you post a photo of your meter?

Thanks so much for the quick reply.
Here is the meter I was using

Set the meter to 2000K, then try the resistance readings again that you were having trouble with.
An autoranging meter makes this much easier. A meter like you have needs to have the range manually selected.

Yup when I first measured I was adjusting it to the nearest range selection that was available.
Tried 2000k and getting pretty similar results to my initial readings.
Would pictures help?

Try putting your meter on 2000 and measure terminal 3.
Posting build photos could help. Getting an autoranging meter may also be really helfpul.

Here is the full results using the 2000k selectors (You replied right before I was about to post this). Also tried terminal 3 on '2000' selector same output.
Also build pic is attached (Tried posting a bunch but apparently hit a size limit or something). Wasn't sure how to snap them so if you need a better view of the terminals please let me know.
This is exactly how it reads on my meter.
Terminal
1=0
2=1
3=1
4=1
5=1
6=1
7=1
8=0
9=0
10=1
11=1
12=1
13=1
14=0
15=0
16=1
17=1
18=1
19=1
20=1
21=1
22=0
23=1
24=1
25=1
26=1
27=1
28=1
29=1
30=0
31=1
32=1
33=1
34=1
35=1
36=1
H1=0
H2=1
H3=1
H4=0
H5=0
H6=045
H7=1
H8=0
RCA Jacks
L center pin = 1 Ground tab =1
R center pin =094 Ground tab = 0
Thank you!

How about the DC resistance between ground and pin 9 on each socket?

I assume that means to use the ohm selector still.
Still using the 2000k selector:
On the A socket depending where I place the probe it shows either 0 or 1.
On the B socket it shows 1
Is it possible that my multimeter is bad?

Set the meter to 2000, not 2000K, then try that reading again.
Yes, this may be a meter problem if you are unable to measure the resistor from ground to pin 9 on each socket, as that's all that's there to measure.

Alright so socket A showed 1259 and B showed 1. Using the 2000 selector.

How about 3, 11, 17, and 25 with the meter set like that?

All with '2000' selected:
3 is 1
11 is 1
17 is 1
25 is 1

1 would mean that you should keep going up in ranges till you don't see the 1 anymore.
I would recommend an autoranging meter though, that was a lot of fussing around to measure one resistor.

Agreed.
I went all the way to 2000k on the selector and it only showed 1 for each terminal (3,11,17,25).
Of course stores are closed for the holidays right now otherwise I would head out. Just curious if its something in my circuit causing the issue guess I'll have to wait.
Thanks again Paul.
