[HBR] Radio design advice

[windy10605 at juno.com]

I helping the GB-1 group come up with a comparable receiver for the AMECO
AC-1 clone transmitter the AMEGLO GB-1. I needs to be simple, 3-4 tubes,
oriented to CW reception, cover 40m and 80m, preferably use octal tubes,
etc. 

What I've come up with as the best alternative so far is something like
the Simple-X receiver of the early 60s handbook using a tuned preselector
covering both 40/80m (pluggable coil), a  Heathkit HW/SBxxx VFO for
tuning 5-5.5Mhz (36:1 vernier), both feeding a mixer with audio derived
AVC ? Mixer output is a tuned 1843Khz IF coil with a 1843Khz crystal
filter (cheap), driving a regenerative detector (no BFO required), and
that drives 2 stages of audio. 

Comments please and octal tube suggestions, plate voltage of ~150V,
headphone output is OK, selectivity is important.
