I am just about to start building this amplifier. The circuit calls for using pairs of resistors in opposite polarities (If we could call it polarity being a resistor), from what I've read that may reduce/cancel inductance. I have never done that in any of my previous amplifier designs, and neither seems to be a common practice. Is that really necessary or did the designer done that the same way he could have used silver wire or isolation feet?
Does it really make a difference to make it worth it to implement that way?

PP2012 - KT88 Hi-End Push Pull Amplifier

Best regards
I don't see anything extreme-higend in this amp. -40 dB of 3'rd harmonic plus grass of higher order harmonics, unreliable solder joints; can decreasing inductance that starts acting at tens of megaherts help? I don't think so.

you guys got that all wrong...its for AC current, if the current goes one way, it goes through one resitor, if it goes the other way, it uses the other resistor

But... but... are we talking about the usual positive-to-negative current, or the physical-world negative-to-positive current for the same ambipolar resistors?

Could be positronic current, or electrons going backward in time.
