Tube type 10 MHz VFO controlled xmtr - ideas?

Am thinking about a 2-3 Mhz VFO mixing with an old surplus 7-8 Mc xtal.

The 10MHz band is so narrow (10.1 through what, 10.14 MHz?) that a
couple of crystals and some rubbering can cover it.

The VFO+mixer scheme is great for a multi-band SSB xcvr but the
complexity really isn't needed in a CW transmitter. Just build a VFO
straight for 10MHz, or double up from 5MHz (lots of 5MHz VFO plans in
all the handbooks) or triple up from 3.3x MHz.
