Carl,

400W carrier, 2500W PEP to the antenna.  At least that's what the BC-610 
or T-213 will do.  I've used both the B&W and a Bud LPF for this 
purpose.  Each is directly attached to the RF out connector.  Tuners and 
all else comes after.

I've run them since 2001 or before, can't remember when I went QRO AM.
