She's alive!

The 10u tantalum was shorted. Replaced with an electrolytic for now.

The top trimmer is very sensitive, it's a small adjustment window to get the phasing. For mine it was about 1/3 turn.

I would like to say the main layout is verified, but the lower trimmer doesn't seem to be doing anything. I was assuming this trimmer would either even out the upper and lower phase shifts, or adjust the height of the sweep, but I can't hear it changing anything. I may swap it out with a larger value to see if that makes a difference.  

I used 3 1458s and matched 2n5457s. Will checkout some other ICs too.
