What about building something a lot simpler, first? There are
hundreds of published receiver designs, all the way from one-tube
regens up; four or even three tubes will give you a darn good little
superhet.
(By using 'band imaging' a superhet can tune two bands without
bandswitching, just by tuning the front end. 80 and 40 meters is
the easiest because you can get both bands just by swinging the
tuning cap.)
>From layout through checkout, such projects take a fraction the
time; you just do not run into the complexities with four tubes that
exist with 16! The late 50's through 60's *Handbooks* have a good
selection, running from a one tube regen right on up.
Looking just at the projects that succeeded, I started out with fairly
simple sets in the 1990's -- four, five, six tube designs. However
even the failures improved my construction skills.
The main thing I did wrong was to build original designs right from
the start. They were certainly educational but a lot of times it was
'education' instead of 'a working receiver.' Someone with the
wisdom to copy an existing design would have done far better.
