I have not put the Hycas together yet but I am speculating that a single stage with 3 or 4 J310's (each with it's on source resistor) in parallel and maybe a 2N5109 or 2N3866 in place of the 2N3904 and suitably biased would have one hell of a good dynamic range. I'll try to take some measurements this week on both configurations

I have the last few of Hycas IF amp kits for sale. This version 2.1 can be used on 9.000 or 12.000 MHz.

Check out my 9.000 MHz product detector and audio pcb.  It has a four pole post IF xtal filter, usb/lsb/cw carrier oscillators, mute and sidetone circuits. A TDA2050 gives superb audio.
