An alternate 36v supply... (9v are sooo expensive!)

Or maybe the wife would agree to a pedal powered charger( you KNOW where I'm going with this).

Greg, I hope you were not suggesting that the wife would be doing the pedaling while you listen.

Cheers,

Well who else is there? The kids all left at 15 to seek a more gentle life in the military!
 
Since we are back on the Quickie battery discussion, I have been doing a little experimenting with different voltages. 62V Lipo, 36V Lipo, 30V NiMh. I had thought at one time that the 62V sounded somewhat (very small amount) better in terms of definition/resolution. Now I think the 30V sounds the best. Not as forward, more 'laid back', less fatigue. I think that may be due to distortion. It appears that distortion in the 3s4 increases with voltage. Here is the data sheet.

Still don't have the Quickie kit yet, but I do have some Li 9v batts on order. Hope it works out good. Seems that somewhere here someone mentioned batteries having different resistances (per cell?) to 'leg go' of current. Faster is better, I'm guessing. I will also be using dual mono (coarse and fine) volume controls, freak that I am about control.
 
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.
 
Eric, you need one of the speaker test systems with the dual mics, then you could really be obsessed with channel seperation. You should should see me set up a cartridge on a TT, the azimuth and I have a real love hate relationship, I actually considered buying a Fosgometer or whatever they call it for as much as an entry level TT, thankfully I was able to convince myself to just let go...

Shawn,

Look at this thread for a dead on way to adjust anti-skating and azimuth.  You should do azimuth first.

This is exactly what the Fosgometer does.  Read the manual and it pretty much says so.
 
Grainger, I think the supermassive black hole at the center of the forum ate your link. It has eaten some of my posts from time to time. Seriously, I think I have read the thread you are referring to. Actually I have had really good results using the Best Tractor from Mint LP. They are made custom for a particular turntable, tonearm combination. So the geometry is precise. I use a digital pathology microscope I picked up used, and use refraction to set up the azimuth. Using this method you adjust based on stylus position and not the cartridge body. It is tedious, but quite effective.

Cheers,
Shawn
 
You got it Jim, I always like a chance to play with my toys. Grainger thanks for the link, that's some great info.

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.

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.

shreekant :)

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.
