@supatrac Now that you have identified yourself as the maker of the SUPATRAC Blackbird. I have a few questions:
1. The thrust box is hung from threads connected to the center post. Do you need to assemble the thread or is it pre-assembled.
2. The tonearm mount seemed to be drilled from under the arm boards. Can you drilled directly from above?
3. Can you provide a SME adapter to your mount?
4. How extensively have you tested the arm with various cartridges? I am thinking of pairing it with a low compliant Koetsu. Any problem?
