[Amps] 160m mosfet linear amplifier problem with ferrite cores

[sasas asasas]

do you mean to test at 1.2mhz with 67 material ferrite or the test at 67mhz and 1.2mhz with the same 43 material ferrite?

   I suggested replacing the broken core and testing at 67 and 1.2 MHz to see if the frequency 
extreme is a problem.
