Default Re: MuTek Pre-amps for the FT290R

I have one of the original Mutek Front Ends in an FT221R. I still have the original Yaesu front end too. There is very big difference between them and the Mutek one is never coming out.

It replaced a JFET mixer with a well terminated diode ring followed by a 10.7MHz 15kHz BW roofing filter. The RF amp is a BF981.

Did they do all this for the FT290 or was that one (as titled) just a pre-amp?
