Newbie question about reversing Phase??


Hello, I just purchased a tube preamp which reverses the phase. How can I then put the whole system in Phase? Can I simply reverse the pos with the neg, and visaversa, at the speaker leads on the back of the amp?? Please help, thanks, Jim

Dc2, there was a previous discussion of this. I had always thought as you do that the contact with direct current should be an outward push of the driver. Now I am less certain. Consider the microphone and the initial impulse of a horn. The microphone moves backward. If this electronic impulse is a positive pulse the driver would be pushed outward, but if the impulse is negative, it would pull the diaphram backward. All would depend on the microphone being hooked up out of phase. I wonder if there is any consistency to this.
Also, it is improbable that a preamp with phono will maintain absolute polarity throughout or between the phono and non-phono inputs.

I have a little unit for inverting polarity on phono but never use it. Most often, however, you can hear polarity differences on LPs. With purist digital players I no longer have the easy choice of polarity on digital. My old parafeed Exemplar preamp could easily have had a polarity switch by just reversing the output side of the transformer.
