Evert,

Take a look at KPA100 resistors R19 and R20.  If they have blue-gray 
bodies, they are likely to be inductive (which causes the problem you 
mentioned).

The new non-inductive resistors have reddish-brown bodies andcan be 
obtained by a note to parts at eecraft.com.

Now off to more FDIM/Dayton fun.

73,
