That is a reverse RIAA board, allows me to feed a line level signal into a phono input to test a phono stage without needing a turntable.
this was a purchase, it is made by Hagerman Labs. Here’s a link.

I just purchased the one listed by Hagerman

Great project. Just as an FYI for others, I'm pretty sure that old glue becomes conductive, not corrosive. Different problem, but just as bad.
The glue... Attracts moisture and dust. The moisture oxidizes what ever metallic metal it comes in contact with. The moisture is also responsible for the conductive aspect. Not corrosive per say. But does promote and enhance oxidation.
I've never actually measured the pH...
Yes, there is a fair bit of original parts left in the unit. The amp did work before the restoration, and sounds much better after the restoration. In my experience, I’ve never had an amp sound worse after doing the work I’ve done to it.

Excellent. I just acquired a Yamaha Ca-1000 I got lucky with this unit and it sounds fabulous. Prior to was boxed up for many years. Wasnt even dusty when opened. I havent replaced anything yet and am debating whether to aside from fuseable resistors and probably speaker relay. Im also going to change the binding posts once I get back panel specially made for this unit from fellow member here who kindly donated panel he had made and had extra.

Very nice. I have back plate coming that fits right behind back, its one solid square piece. I just need drill and find bindig posts that are short. Parts express has some that I think would work well.

With the assistance of all
Great job! I just came into possession of the same amp (with the separate tuner (610)). Someone throwing it out by the side of the road in my neighborhood. I have a reasonable electronics background, nothing profound and never anything this large, but eager to take on the project. So I have a quick question about sourcing the replacement caps and Tr's. So do you order them as needed? or did go through the schematic and buy the entire list in bulk? And do you have a spreadsheet of the parts like your inspiration provided? https://audiokarma.org/forums/index.php?threads/project-yamaha-ca-2010.899468/ . Thanks!
I typically stock parts like Semiconductors and some caps, but for large restoration projects like this, I make up a BOM and order everything on the list. Most of the time I don't need to each part in bulk, places like Mouser and Digikey typically allow you to buy in multiples of one. Of course if you're planning on doing multiple restorations you can save money by buying in bulk. Unfortunately the spreadsheet I have for this is incomplete and may not match the list I included throughout this thread. I'd recommend following Super Noob's bill of materials and cross reference with the lists I provided in this thread. Many of the parts are identical, with the big changes in components being in the amplifier section. If I remember correctly, the power supply, tone board, and most of the preamp have the exact same components with the exception of a few extra caps on the preamp board in the 2010 that aren't populated in the 1010 board. Hopefully this helps you out!
