Hello Ron, and welcome. I am also a DIY person.
My latest build was the completion of a Lampizator DAC. (sadly they are no longer offering their DIY products).
I have built several turntables, speakers, preamps and tube amplifiers. I have lots of parts, diagrams and schematics.
I am willing to share and help with any projects you may have.
DIY is a lot of fun, a great challenge of your abilities and very rewarding.
Keep at it and have fun
Dave.
