I'm trying to 3D print vacuum tubes and the 6922 is at the top of my list. I'm trying to figure out how to 3D print the actual vacuum.
6922 tube selection
Time to retube the C-J pre amp and amp. Looking at Genalex Gold Lion tubes at $46.00 each vs Electro Harmonix at $26.00 each. Need a total of 7 tubes. (4 for pre amp and 3 for amp). Any reason to spend the extra money on the Gold Lions? And, any need to spend the extra $5.00 per tube for matching? Thanks for the feedback!
