In the Thread: Copper Mat on a Micro Seiki Gun Metal Platter
Post Subject: And I'm not trying to sell it!Posted by Wellington on: 7/23/2017
It is entirely possible to buy a good flat CU-180. I have two from eBay there were correctly advertised as being flat. I have also seen them on eBay as being "slightly bent". Those you avoid.
But I agree that a replica is a real possibility. I never said that the CU-180 is the only possibility. It is the only one with which I can confidently report excellent results. In fact I have seen copper mat replicas on eBay. If an experienced machinist properly machines both sides, and expertly handles any annealing and post handling, a good flat "copper" mat should be the outcome. There is the question of duplicating the alloy of the original CU-180 mat. How much does that matter? I don't know.
Micro Seiki also made the heavier CU-500 mat which is quite rare now. I have not used one. There was another vintage manufacturer of copper mats. The name escapes me, but I want to say "Final Sounds."(?) I also recall seeing at least one recent manufacturer, mainly appealing to the Technics crowd who love the CU-180.Rerurn to Romy the Cat's Site
