I never made a Heathkit but did over time get some Practical Wireless
designs to work and some in Wireless World but it seems these days the
overall the "Tech" has changed for a lot of applications.
Take a tape recorder almost no one uses these for domestic use anymore
its all digital. Now make a digital Card player?. The chips are so
bloody small you'd need specialist equipment to place them, hot air
stuff etc far beyond that the Ampex iron can manage. The software well
perhaps, but all in what are you going the learn and make?.
Take a CD player, same again but a transport and perhaps you might be
able to do in conventional say 14 pin plug_able chips but why do that
when you can do all thats required on one umpty pin one but there again
soldering it to the board if large surface mount?.
Perhaps the audio amp is still a possibility and perhaps the only likely
one now plus perhaps speakers if your good at wood fettling.
Course valve amps can be a good proposition but is there that much of a
market for them?.
As to ham equipment the few I know seem rather proud of their multi
function kilo pound unit that does a lot in a small space,, now don't
all come back at once and say "I've just built a 1 K linear for SSB"!..
Course the fM tuner of olde?. Now best done in the digital domain and a
DAB kit radio?.
Perhaps the kit has had its day but saying that they still can be useful
for some apps, we often need to knock up custom bits and bobs and one
instance recently called for a telephone remote controller the one here
from Quasar kits proved just the job and it was still enjoyable
soldering it together it is in kit form;). Least you feel you've made
something useful:)....
