So Close...Yet So Far [resolved]

Greetings from the Great North!

I finished my wonderful soldering journey with the Moreplay only to find myself at the dreaded voltage problem on the final page. I thought I would post a cry for help based on my Resistance and Voltage Checks first before posting images, as the numbers may tell more than photos for now.

I passed the Power transformer test. I passed the glowing 6v6 test. I passed the Raw B+ voltage test. My numbers for those were spot on.

For the resistance Check the main incongruencies with expectations were:

Terminal 9 - OL
A5 1.94
A6 OL
B5 - 215
B6 - Ranges

Voltage Check DC

Terminal 1.  -1.2V
Terminal 4  - 0.1
Terminal 6 - -1.2
Terminal 11 -1.1
Terminal 14  - 0.1
Terminal 16 -  -1.1

I should note that I did try the Moreplay in my system (I was not sure if I was just messing up with the multimeter and was off by 1000 or something) and there is nothing. As per my reading of the "rules on p.58 I could proceed with the voltage check. I wore rubber boots and had a hand in my pocket [with Alanis Morissette playing on my phone].

Any thoughts before I go through the entire circuit tomorrow? I thought my solder points were good, and I think my capacitors are in the right directions.

So close...many thanks.

On your resistance test, terminal 9 should read 10k ohm, and that it reads OL suggests your vol pot red lead isn't connected to terminal 9. Its not clear to me if that would cause all the other issues.

Actually the A6 resistance also should not read OL either, that implies it's not connected to anything. For the A&B 5&6 pins I recommend setting your ballence pot at about the middle of it's range. You should then read values like 40-60k ohms, and A5 & A6 should be almost the same and B5 & B6 should be almost the same. If yoou don't get that there's a wiring issue there too.

Definitely don't try to use a piece of gear you know isn't working in your system, as that can cause lots of damage to other components and you aren't really learning anything by doing this. 

Can you post some photos of your build?

anthonynchandler:
I am attaching a selection of images which might help if I connected something in the wrong place. Everything seems attached properly, but I could be wrong. Absolutely my mistake to attempt a hook up without 100% measurements being proper. I thought that with the passed tests on the previous checks I may have simply been measuredly those points incorrectly. My mistake.

What I found strange was that the misreadings both seemed to be off of the tube sockets in the same spots for both A and B.

Anyway, any help offered is greatly appreciated.
