Calling folks who have built Gaussmarkov Spring Reverb

Having taken some months off DIY, I decided to pull an unfinished project off the shelf and grabbed Gaussmarkov Spring Reverb because I only needed a tank and pots to finish it up. So I sit down with it and notice two things:
- The Gaussmarkov website is still up, and with a 2018 date, but looks different and I can't find the actual project packaged/zip files anywhere.
- The spring tank connections are not obvious in his diagram. I'm assuming pads "4" and "6" on the S side of the transformer connect to the tank, but which is in and out? What's the mystery "spring" pad on the top side of the board? Looking at the schem didn't help

I will post a link to the original files which I have squirreled away on my work computer...

But in the meantime I wondered if any successful builders had anecdotal advice.
I have parts on the way and would love to finish this thing but for now I'm confused.

Thank you in advance!

Bump, with the project schem and diagram, which don't appear to live on the web anywhere at this point. I'm really grateful for the help. (My progress on this was slowed somewhat: my parts order got mistakenly shipped to Pennsylvania instead of Oregon, because the barcode printed wrong; when I did finally get it, most of the pot values were wrong. So I've got some time to figure this out before my corrected parts arrive!)

Specific questions:
How do I connect the reverb tank itself?
> How do pads 3 and 4 connect to the spring reverb?
> What's the mystery pad "Spring" following C11? 

I'm assuming from the transformer 3 and 4 are output and ground into the spring's  input. And the spring output goes into the "Spring" pad.
Gratefully,
- Strategy

From the schematic and the PCB-Layout "Spring" is the pad to connect the output from your reverb tank to. I have not built it but this is quite certain from the diagrams you provided.

Thanks, that's what I suspected but wasn't sure I was reading it right-- thank you!
