Battery Sale!

I'm loving the Quickie so far! Using it with Emotiva MiniX a-100 to HE-500 headphones.

Check out my impressions here: https://www.head-fi.org/t/551345/hifiman-he-500-he-as-in-high-end-impressions-and-feedback/9645#post_10035084

Anyways, I was hasty to buy batteries to power the baby up, I ended up spending $22 at the local pharmacy for a single set of batteries.

But I just saw this great battery sale that I wanted to share: Sony STAMINA PLUS Alkaline Batteries - http://www.woot.com/offers/sony-stamina-plus-batteries-5-sizes-1

$12.99 for a pack of 12 D cell or 9V.
 
Speaking of batteries, does anyone know if the D cells and the 9V drain equally? Do I end up replacing all at once?
 
I don't even own a Quickie but bought AA, AAA and 9V.

I get the daily Woot! and had been considering it anyway.  These are good prices.
 
My four 6xAA batery packs cost me $8 and I got 48 AA for $10.... not sure how long its going to last... last I checked it was just about 34v after quite a few months IIRC. I have already had to swap out my D cells about a month or so ago. Ill never buy $$$ 9V batteries again. The cheap AA are too plentiful.

Based on the data sheets for the batteries, they should last about the same time, roughly 200 hours.

In the real world, it seems that batteries in perfect condition that might meet data sheet specs are pretty uncommon. I suspect @mortron has a good idea, in that AA's are so widely used, they are both cheaper per watt-hour, and probably fresher, than any other size. You can parallel a similar number, half for each tube, to get a similar-lasting filament battery. You may have to pay more for the battery holders than the Quickie though!
 
I've also found that the green and black batteries from R@dio Sh@ck will die rather immediately right after you start using them.  I used a fresh set of four in my Quickie for about 10 minutes, then pulled them out and set them on the counter to go do some tweaking to the circuit.  When I got around to putting them back in 3 weeks later, all four were completely dead. 

 
I use them for the 36vdc.  Been wanting to get rechargeable D cells but they and the appropriate charger are expensive.
 
I've heard rechargeables don't charge up to the max 1.5v or 9v. Might be okay if you have the PJCCS upgrade.
 
The tubes and the amp are designed around 1.25v and 30v, expecting a range of 1.0v-1.5v and 24v-36v over the battery life. So NiCd and NiMH at 1.20 volts/cell and not losing voltage as they drain are about perfect.
 
I ordered up (3) eight AA holders and am going to do the 24 piece AA conversion too.  They were not expensive.

Good idea on the AA's, thanks!
 
I found my rechargeable's at All-Battery.com. The brand is Tenergy for both D cell and 9v. I have the Premium in both D(8.49ea) and 9v 200mAh (4pack $14.99) which are white body blue lettering.

I also have the light/dark blue set D cell (8.49 ea), and the 9v 250mAh (4Pack 16.75). They shipped them fast and they have worked great in my Quickie. Still in awe over the sound from a bone stock Quickie.

Hope this helps? ;)

After some research I have found that 24 AA batteries cost about the same as 4 nine volts and have about 4X the capacity. 

Sweet.
 
I can't recall how long ago I installed my 24xAA packs but I know I'm on my second set of D cels and my packs read a total of 34.2v... cheap as chips to power and I still have another 24 cells.
 
Picked these up at the hardware store today.  10 bucks each.  48 AA & 9 D.

In sexy little wood crates too!

How do you hook that up to the Quickie?
