My RCA AR88d general coverage receiver (spine crumbler!) has a standby position on the rotary power switch which therefore obviously cannot be bypassed other than at the wall socket. That article suggests that RCA didn't know what they were doing? Hmm. Open verdict on that one. My AR88 dates from the second great war and I've been custodian for the last forty years. It is still going strong but I did have to substitute an audio output transformer about a year after I got it.
I also have an HRO which doesn't have a standby switch, but of course that receiver has a separate power supply. I have no issue with the waterfall of information within that online article, partly because I admit I skimmed it and partly because it's beyond my pay scale, but just as with my 30 watts "Session" combo valve guitar amp, I'll stick with deploying the standby switch because it hasn't let me down so far. Hardly a scientific approach but I'm not about to reinvent the wheel with an extremely tried and tested technology. I thought my AC30 had a standby switch which reveals how the passage of over three decades can dim one's wits. I still mourn trading on my VOX (for that Session amp as it happens).

The article is certainly convincing-sounding. Perhaps that is why there is so much variation in the market: Some Fender amps have no standby switch, the AMPEG V4 has one and the manual suggests 30 seconds before applying the high voltage, and the VOX AC15 manual say to wait a full 3 minutes before applying the high voltage.
I always figured it was driven by the particular differences between the circuitry rather than misunderstanding/misinformation and tradition, but now I do not know. I have also read articles that sounded equally credible that explain why the standby switch is important and needed (I cannot recall the details just now), so I will still use mine but I will not leave them in that state for extended time periods.
