There a lot of record shows in LA/San Diego area. The two that I normally go to are the Sequoa Swap Meet (in Buena Park) every last Sunday of the month and the Pasadena City College Swap Meet (in Pasadena) which is help on the first Sunday.
The only high end equipment swap meet that I knew was held by Upscale Audio. You may wish to check with its web site.
