Thank you for the reply, Jeff.R1, C1, R5-R8 all look correct to me. Some of them were soldered from the front and then again from the back (I used the wrong tip on the front during assembly, went back with a "chisel" tip to reflow the solder joints from the back after assembly), so they look not so great on top. I also went through RG1-RG11 and all of those are correct, too. Which leaves me with the gain knob. Is it possible to put the gain switch in backwards somehow? Here are pics of the mentioned sections:https://www.dropbox.com/s/njob03rt28953hp/20190401_115508.jpg?dl=0https://www.dropbox.com/s/wa2h9nj5r21vkym/20190401_115502.jpg?dl=0https://www.dropbox.com/s/inxz6r1wfud2a9i/20190401_115458.jpg?dl=0https://www.dropbox.com/s/az898f7ppdld69f/20190401_115454.jpg?dl=0I'm at a bit of a loss.

I have gone through and cleaned up all of the solder joints in the areas you pointed out are before TP2 and I am still getting 109mv at TP2. I am at a bit of a loss here. Any other ideas on things I can try?https://www.dropbox.com/s/rfbauorn1grlqsw/20190407_151525.jpg?dl=0https://www.dropbox.com/s/p12vewssq5hpqpj/20190407_151510.jpg?dl=0Thank you for your assistance, Jeff.

#facepalm Thank you so much for taking a closer look. I'll go back through everything again and see what I can find. Brandon
I did give you those part #'s to check previously.
The question probably has been asked before. Is the double-stick foam tap required for installing the input transformer? I don't see it in the kits. What is its purpose? I guess it helps holding the transform in place....
One last question, is C3 33uF 60v or 25v? In the BOM it says 25v. The only 33uF capacity in my kit is 60v. Since 60v is greater than 25v so I think it should work. Not the other way round, right? Thanks again,Leon
