Happy New year to U also, Richard. When it comes to AA5s, I think that Everyone built them as cheaply as possible. Throughout the history of electronics, steps were taken to reduce the steps required to manufacture radios. The printed circuit board is a perfect example. eliminating power transformers, then remove the filament dropping resistor or cordohm was another. Even before printed circuit boards, reducing the bends required for a chassis was another step. So was the multiple capacitor "can".
Of course, the real revolution was the monolithic integrated circuit. Amazing to look at the parts count for the 30 tube RCA 630, then to some of the last USA built RCA color TVs with about 6 VLSI ICs, a flyback, a few transistors, controls, the CRT, a speaker and little else.
Unfortunately, the next step in lowering prices for electronic equipment was to offshore the entire electronics industry! We will live to regret this.
