Shawn,

AAA came to swap my wife's flat with the spare as I was about to post so this got delayed 40 minutes.

Nope, my gray hair ate into my brain cells and I forgot to paste the link I had saved.

I edited my previous post adding the link for better continuity.  

The 'scope method is dead on.  The azimuth is right when you get the best balance between right and left channels.  That is a null when you are inverting and adding.  The same thing goes for anti-skating.  If the stylus rides one groove more than another, you get the same kind of imbalance.  If you have both of them off neither will really zero.  Then you have to tweak them down till you get zero on both azimuth and anti-skating.

I like it because it is pragmatic, logical and you can see it working.  This is the same method used by the Fosgometer.

It's shocking how good this combo sounds!  I use the Quickie with my home-made tube amp based on the Dynaco ST35.

Rob,

That looks like the back of my stereo when it was tri-amplified.  Wires everywhere! 

You charge the batteries in parallel, right?

Nah, I just charge them one at a time.  I don't get to listen as often as I'd like so I have the time.  I have a CTEK 800 smart charger which does a great job.

The quickie doesn't draw that much power.  I even left it on by accident for almost a day and the batteries didn't even drop 1 volt.

@corndog71, I LOVE those pictures! That's what it's all about, experimenting and having a ball doing it. Quickie hit the market specifically to return to an aspect of the original Foreplay - something so cheap you can feel relaxed about playing around with it, yet with some decent sonic potential.

I do like the look of the 12V's in series! Quite massive!

Greg - I could get into dual mono controls. Honestly I feel there would be a very real use for them, beyond pure paranoia etc. I frequently 'think' that one channel is louder than the other. I can easily move the MMG's an inch or two forward or back to compensate. I bring them 'out' to listen anyway. I wouldnt be able to do that with 150lb speakers. The 3s4's are rarely matched.

At times I too feel the same way. Strangely, if I have changed or not broken in a cable and put them in then my left channel gets louder and it takes a few days for it to settle down. This happens irrespective of the amp/source config. Maybe a dual in the quickie may help.

Has anyone thought about using three 12volt...

Bernie.

Yep.

Looking at doing this. How did they work? Sound?

They work very well.  After a month of almost daily use they're still holding steady at around 37 volts.  As for the sound I'm not 100% sure it was the batteries but the quickie seems to sound a bit more relaxed than before.  If there's any audible difference it's very subtle.

I didn't do it for sound quality.  I wanted to save money as I was going through a lot of 9V batteries!  For what I spent on the Power Sonics (around $55 from Amazon) I figure they'll start saving me money after about a year of use.  I wish they made 1.5V batteries that hold a charge as well as these do.

cool - the zen of lead/acid! Might be fun to try.

That's great. Wasn't expecting a huge sonic improvement!  Just didn't want the sound to go south!!!  The SLA batteries are next on my list!  Tired of the 9v burn!!

Just a quick note here. We've been talking about development projects, and one of them is an AC power supply for Quickie. I have some ideas and am hoping for something that fits under the chassis easily. This is a long way from a product announcement, just a little hint for the enthusiasts who are following this thread.  :^)

The 300B preamp has reminded us how good directly heated filaments can sound, and we're starting to take Quickie more seriously. Many thanks to the Bottlehead community for their enthusiasm for this little "toy"!

How have you got the batteries hooked up, I wonder if there would be a cool way to make them part of a chassis.

Nice looking stuff! How much power do you get from the Dynaco?
