Cool !!!!
And WEIRD electronics .... like wire color coding (*all* blue, why bother with others? ) 200 contact rotary switches where only 4 were used, Round to Dip to Round Op Amp pinout adapters, weird trimmers, Bakelite molded caps .... metallic round case Op amps and transistors ... coupled to a modern well made front panel, modern graphics, good silkscreen .... the works.
Mind you , when I started I used metallic BC107 and round case 741 so was not that far away ... but it was 1969 !!!!!!
Of course, designers use what's available, and get good results, proof that end result lies in the *design* and not in the *parts* .
FWIW I'm absolutely certain that I could make almost the same amplifiers, get almost same sounds, if all I had were 741 and 2N3055, go figure.
PCBs would be somewhat larger and complex, amps would hiss more, but no big deal.
Now that I think about it, maybe some day I'm bored I'll make some transformer driven power amp, 2N3055 output, plus 741 and BC*** preamps or just the bipolars , just for fun.
Last week my digital tester battery died, all I found in random drawers still in the original package were dead and leaking (proof not everything NOS is good
), it was Friday 11PM with a customer breathing over my shoulder and I had to dust an old needle multimeter, again with dead leaking AA batteries so I coukdn't measure resistance or diodes but at least the voltmeter worked perfectly ... as would the ammeter if I had needed it.
The time machine indeed.
FWIW next morning I bought a 9V battery for the digital one and a couple AA alkalines for the old workhorse which had saved my bacon once more.
