I had a problem with the 454's. Using all the supplied parts, the output
was low and the current draw was high. This was solved by replacing the
910pf cap between the collectors with a smaller value. I never tried it on
an antenna then. One of the 454's died because the radio output was too
high - my mistake. Once I get the amp working, is there a way to reduce the
input to the amp? I've seen some designs with a simple voltge divider. Would
that work OK?

Thanks,
Chris
