Done this many times with various Heathkits (I was once a Heathkit tech, long ago) and industrial electronics, here is my favourite:
Heathkit HR-1680 - a low-cost but reasonably high-performing ham-band radio receiver. With the audio CW filter on it could pick 0.1 uV signals out of the mud. Not quite the same class as the SB-series, but damn! it worked good. Sometimes the front end would oscillate if the RF gain turned up too high, easily cured with a resistor in series with the wiper hot end of the RF gain control.
Its main problem that many Heath customers complained to me about was that all signals were S9. The S-meter tended to hang in the middle, only very weak or very strong signals pushed the needle below or above S9. I studied the circuit and came up with a modification to make the S-meter behave properly, actually truthfully indicating the relative incoming signal level. My Customers were happy.
Heathkit Engineering approved my change, to be applied whenever a customer complained about this defect.
Could relate many more stories, but the Tek scope contest is probably limited to a single entry. Besides, would not want to get started on the SW-717 or the CO-2500!

What have you got against us Aussies and other infidels? How about if I promise to come and collect the scope in the US if I win (I reckon it would then work aout about half price..... :-) If not, you'll miss out on at least 2 stories..... (and I won't re-enter the fixes I did for Max :-)
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
