Not sure. Maybe it happens in the 2nd stage, i.e. the 2N3053. 4Vpp should still be managable.

Yes, looks we have the same ideas :-) I'm really looking forward to the new results. Thanks for your comments and suggestions. It makes me even more optimistic. BTW What would this hobby be without having problems from time to time !!?? :-) OK, the show starts now. Must go out before it becomes dark... Slept until 14 o'clock local today ;-) 73, Stefan/DK7FC > > 73, > Roelof, pa0rdt
