*Update (December 8, 2022): Changes in plywood cost and availability have forced me to seek an alternative to the Baltic Birch that I have been using for years. I have found an alternative available in maple (3/4") and birch (1/2") that should be less expensive than what the Baltic Birch has risen to. An added benefit should be a reduction in the overall weight cabinet weight.
*Update (January 20, 2021): Please keep in mind that I still have plenty of Diamond Blue blue-check tolex available.
