Play the 60Hz tone into the Kaiju hooked up to your speakers and measure the AC voltage between the speaker binding posts.
Hum Pot adjustments [resolved]

Now feed the tone into the BeePre and hook it up to the Kaiju.
Now that you have lost the channel, I would restart the checks you just completed.
You appear to have substantial loss between the RCA jack and the center post of the D jack. What's the AC voltage at the center pot lug?
0V at C3 means the signal isn't making it out of the 5670 stage. I would expect a DC voltage to be off on the C4S board if signal isn't getting out of here, but admittedly that's not always the case.

Can you post a photo of 4 pin socket and the 0.1uF cap mounted behind it?
Ok, on that strip if the 0.51 ohm resistor touches the resistor going to A3, you'll destroy your 300B, so I would slip those 0.51 ohm resistors in toward the 4 pin socket some more.
Where the 0.1uF cap lands on the terminal strip on the 4 pin socket it looks like you need a lot more solder and heat. Where the white wire jumps from there 5 pins over looks like it could also use a bit more solder.

Yes, that is a promising change.
It's possible that you have something that's loose and flipping the chassis plate around is moving the intermittent connection.
Once you put the Kaiju back in your system, you'd want to play the 60Hz tone back into it directly to ensure that it's still passing signal before looking for problems elsewhere.

If you can play the tone through the amp into your speakers, then you need to hook the BeePre up and try with that.
If you only get one channel of output from the BeePre, swap the interconnects at the BeePre to see if the dead channel moves to the other side of the Kaiju. Be sure to try both cables on both channels to rule out cable problems.

If you take your BeePre and feed the left output into the right channel of the Kaiju, does that work?
