It would have been better to put some more discs on the hv itself. 1000pF(?) at 1.8MHz is not much of a bypass. > cheers, Hans... -- FAQ on WWW: http://www.contesting.com/ampsfaq.html Submissions: amps@contesting.com Administrative requests: amps-REQUEST@contesting.com Problems: owner-amps@contesting.com Search: http://www.contesting.com/km9p/search.htm |
