My training is complete for now. Speedball installed with no issues. Nice to have a small solder tip. What a cool project. Much obliged to all the work put into such a fine sounding headphone amp. Keep the rubber down Doc.
Touch up Volvo silver green metallic. A couple coats and a few coats of clear. Funny thing as it heated and cooled it made a crinkle coat which looks very cool, but almost impossible to capture via a pic. I am working on it. Thank you!
