a couple random technical questions

Hi,

It has been a while since I built the Quickie, but don't remember seeing anything on ESD.  Is that because the components aren't particularly sensitive?  Also, is the Quickie phase-inverting?

The Quickie is polarity inverting (all Bottlehead preamps ever produced invert polarity, except the Submissive).  Resistors, capacitors, batteries, and tubes aren't ESD sensitive.

So does that mean to get the best sound the positive and negative should be switched?  (hook up + amp to - speaker and vice versa).  Thanks,

Dave

Does your amplifier also invert polarity?

You can listen to it both ways.

Paul,

The amp doesn't invert polarity..  It's kinda fun to see that there are still things to play with on the Quickie!  Just changed the coupling caps to K75-10s, and got some black gates to replace the 150uf caps.  So much to tweak, so little time  :

This is just one place where a polarity flip can happen. It can happen in every other piece of gear and at each driver in your speakers. All that matters is the polarity of the drivers.

The worst thing about keeping absolute phase in your system is that there is no standard on recordings.  Some invert absolute phase and some don't.

... and many multitrack recordings are different for different instruments ...

i tend to like the sound of woofers/subwoofers out of phase.  It isn't as loud as in phase, but has a tighter sound.  What would happen to tweeter sound?
