Nowadays, to manufacture an HF RX, with all the concomitant
high density ICs that are around, the biggest design chore
is to cut out the opening for the LCD display on the front
panel.

But, looking in detail at this EA12, almost every facet of
it has involved intricate design and manufacture if only the
mechanical components are considered, and all this from the
days of pencils and drawing boards, long before the era
of computer aiding.

Firstly, there is the aliminium casting for the front panel, and
secondly is the rotary arm coupling to the tuning condenser
to linearise the frequency coverage, amongst many other mechanical
achievements.

Clearly the Stratton people knew their onions when it came
to designing and producing radios.

My gast has never been so flabbered; no wonder it had taken me
so long as a tyro machinist to not (yet) succeed in my own efforts!
