Crack Speedball upgrade help.

Im sorry that i keep plugging in the 6080 I'm just excited to use it.  but the R1s are not switched, I can read a clear 31.2 and 31.4 on both of the R1s on the main PC board.  but the smaller pc boards are reading around 180-190 for about 2 seconds, then drop to 0. Still reading a 180 on both 1 and 5 with only the 12AU7 in.

Ive checked the wiring multiple times, and again. I basically have it memorized from the amount of time I've checked it. Again, one of the LEDs on the small PC board is off, just above the circular 2n2907
 
now 1u and 5u are at 0 voltage and 2u and 4 has a voltage of 245, and none of the LEDs are on on the 9 pin, which i probably shouldn't have touched but i messed it up. Im starting to want to give up this, and I'm really thinking that the speedball upgrade is not something beginners should do. If you can help thanks
 
Paul is the one to listen to here of course.
I am just a fellow bottlehead who wants You to succeed.

It wouldn't hurt posting some detailed photos of Your curcuits from all angles.
Maybe something can be spotted.
 
Look, my wife is yelling at me saying I lied to her because i told her id only be building the upgrade for a night or two, its been a week with no end in sight. Please don't advertise that you can build this upgrade with only the crack under your belt. Every time i make progress i notice other things don't work, and this has happened multiple times. I really want to use the product for the reviews, but the costs are starting to outweigh its benefits.

If you could tell me how to fix 1U and 5U to a normal voltage, that'd be great. If i can't finish this thing soon, my wife will finish me
 
We are trying to help here. It sounds like you are frustrated and need to take break from the kit for a while. I would suggest taking a night or two off. I'm not a marriage counselor and this is a bit beyond the scope of our regular tech support but it seems like it might be prudent to smooth things out with your wife. Coming back to the project refreshed usually helps to get things sorted.
 
I know your not. I'm sorry I'm just venting because of this whole situation. Please just tell me what to do next, I have about 2 hours to myself before she gets back and I'd really like to get this thing to work

It sounds like you're going from very high voltage to no voltage, and never nailing down anything in between.

Since you are confident that you have the correct resistors and transistors on the boards, and have them wired properly, the intermittent nature of this may be due to a flaky solder joint.  Additionally, if you have two pins of a transistor touching on the bottom side of the board (for example, by a solder blob), then you will also run into issues like this.
