Title: Anyone have layout of soldano X88R?
Post by: chaohore on July 31, 2025, 02:13:40 pm

Hello, I am interested in building a Soldano X88R. I have tried to find the circuit or PCB layout and noticed that many people have successfully built it. However, I haven’t been able to find the layout for the bottom board.

Would you be able to share it with me?

Easiest approach would be to locate a schematic and then use that to figure out where everything fits onto the board


Edit: easily found the preamp (should give you some clues)

I found this site with some pics that can be saved and zoomed in to see values, it may help,

Try image searches for X88R pcb and other keywords, I tried "soldano x88r pcb boards" on Duckduckgo search, but google may bring up others,

I find image searches sometimes gives good results as a link to a site that would not come up on the main search
