TPA 3116 vs the tripaths

the UPS battery packs are really tough and have a good service life here is a example from Belkin this is a 2 pack of batteries wich is what I need for a +-12v system dual ac.,
Product Description:
Note: Manufacturers change battery specifications without notice. Please inspect your old batteries to verify the quantity needed, terminal and battery sizes.

Brand New First Quality Factory Direct
Sealed Maintenance Free
The valve regulated, spill-proof construction of this battery allows trouble-free, safe operation in any position. There is no need to add electrolyte, as gases generated during charging are recombined in a unique "oxygen cycle".

Long Service Life
A dependable service life can be expected under normal operating conditions.

Long Shelf Life
Low self-discharge rate allows for storage of fully charged batteries for longer periods of time before charging is required. Lower storage temperatures will further extend shelf life.

Wide Operating Temperature Range
May be discharged over a temperature range of -40°C to +60°C (-40°F to +140°F), and charged at temperatures ranging from -20°C to +50°C (4°F to +122°F).

Rugged Construction
The high-impact resistant battery case is made either of non-conductive ABS plastic or styrene. Large capacity batteries frequently have polypropylene cases, all of these materials impart great resistance to shock, vibration, chemicals and heat.

Specifications:
Must use your existing hardware to connect batteries
Existing/New fuses may need modification to fit

FWIW, I should eventually have some info on the subject of battery power. I am building my b/b board for use in a sailboat (inside cabin), where it will run off the 12vdc system. I also have a laptop brick for home use, and am curious to see if I will detect any differences. At the pace I do things, however, it will probably be a while before I have anything with which to experiment. But I'll report in when I've completed it.

Sounds Good Good Luck On your Project.
 
Just installed a matched set of GE 5670w tubes into my chinese 6z4/6n3 pre-amp from YJ. This is feeding my tpa3116.

The tubes make a very noticeable difference in the sound.

for less than $20 on ebay, I think this is a VERY worthy upgrade for anybody running this combo.

Got the tubes NOS, matched, still in original boxes and including a xerox of their data sheet HERE: http://www.ebay.com/itm/SWEET-MATCH...pt=Vintage_Electronics_R2&hash=item4ad58dae62

I too have NOS GE 5670W tubes in my 6N3 3 tube pre-amp also feeding a TPA3116 (stock). Wait till they burn in awhile, they get better:music: I know it's hit or miss whether the Chinese tubes supplied with these preamps sound good or bad. Although mine sounded good, the GE's do sound better.

I got mine from probably the best E-bay seller I have ever dealt with. They were packaged like they were being shipped to the moon! Tubes in original boxes wrapped in foam, in a new HD shipping box and shipped across the country with 2-day expedited shipping. The inside box cover even had a hand written personal "thank you" note. Mine are not a matched pair, but that certainly hasn't affected the SQ to my ears.

More nube than mastermind but here are three options.

You can buy a PS which has a barrel plug that fits the red board. They're cheap as I bought one off Amazon for $7.

You can take your PS to Radio Shack or equivalent store and pick up a female jack that fits your PS barrel plug. You then run two wires from the jack to the board. You'll need to solder these or use small crimp on female connectors. The jack can cost almost as much as a PS.

Cut your barrel plug off, skin the wires and attach them to the board observing correct polarity.

PG - does the eBay item #191014597793 look like my solution?
 
Someone save me from this TPA addiction. :tears:

With the firing up of the green board this morning I think I've tried all the colors. And guess what, they're all winners.

Can't say how the green board compares to the others yet but I do like the fact that there's no on/off pop sound. Lovely combination as expected with the 3 tube preamp but less than spectacular with the solid state TC.

Here she is without the top cover and although I'm using the hefty 19v PS I can't tell any difference in output from the 12v that I use in the other TPA's.

Nice work again! I might upgrade to green boards because of the annoying on pop with my setup. But I need a little coaxing... hope there is an amp shootout in the works.
 
For those of you suffering from the speaker pop noise, wouldn't one of those speaker relay boards offered by the same vendors clear up that problem? They're only a few bucks. Seems like they would do the job, yes?

I considered something like that - but the ones I saw needed different voltages than what I alread had for power in my amp. That and it was another board taking space up... but yes seems like they could do the job.
 
guys- i'm about to assist a friend in ordering this finished amp, and i'm wondering if anyone can quickly point out which power supply is best to go with it?

many thanks
 
that's quite a can of worms there.
But an easy answer is any laptop brick that gives less then 26v and 5 amps.
so to be safe get one in the 21-24v and 5 amp range.
