Peter I now have the prototypes completed of a composite material cover to replace Astron 35A size power supply covers.
This solves the acoustic noise problem. The new cover looks terrific and is a 1:1 swap with the old one. I went through *exactly* the same problem you describe, and then buying the same replacement supply, then modifying it, ad nauseum, before fixing the original issue. I expect to be able to produce these (it's done on a CNC machine) in the coming weeks. I have several requests already. I do not yet know the cost but it won't be outrageous. Would this interest you? It has certainly interested others! 73 Steve KZ1X ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
