Weirdest Tweak Ever
My weirdest tweak was back in the day I had a Dynaco 400 amplifier that only had one power supply for both stereo channels. So in order to not deplete the power supply on large transients in one channel I reversed the tone-arm wires in my then turntable on ‘ONE’ side of the cartridge and the same on the corresponding speaker. So the left side of the cartridge was wired out of phase and the left speaker was wired out of phase as well – thereby putting the left channel back in phase with the right channel.
This was supposed to allow the single power supply to operate more efficiently and with less strain or overload potential if a large transient was required on any one single channel.
This is not that weird, and it does work with some amps. For a long time I owned a preamp that had both normal and inverting outputs, and I drove my power amp with the channels 180 degrees out of phase and then back again at the speakers. The bass content of a lot of recordings winds up being mono, so this kind of hookup draws from both power supply rails more or less evenly, rather than just one.
I don't think I'd bother with this now, but it might be useful for some people.
