I am the original purchaser of this tube amp kit. Through chip amps, Tubelab projects, commercial items, and other avenues, I never built this kit. The plastic bag the PCB came in is open when I inspected after purchase but that is all. The kit is complete. It’s been on the shelf and the downsizing is in full swing.
Currently unavailable commercially but here is the link for more information.
