The T-AMPhitheater... Keeping the tunes playing while building the Deck...



Hopefully this will not be as large an image as it turned out to be on my hatchet job of a site

Hey Seabear--

Looking good! What are you using as an AC adaptor for the amp? And where did you get it?

Thanks!
Rich

just one of those so called Wall Warts, from a battery charger.
I think it is 12.5 volts and 5 amps.
Sounds great!

Am I going to hear any noticable improvememnt by going to one of those 13.8 V power sources as oppossed to the 12V wall wart that I am using now?
Is the extra 1.8 volts going to really do anything?

Seabear

The most important thing is that you're wall wart is NOT putting out more than 13.8 volts. Some, though rated at 12V put out more than 15. The T Amp's chip will go up in a puff of white smoke (bad) if you give it too much juice.

If you have a multi meter you may want to check the output of your wall wart.

BTW, you get a bit more volume with more volts but 13V is just fine.

Thanks,
I'll dig it out and check.
Have you looked around the net at what people are doing with these T-Amps?
Pretty amazing stuff.

Where is a cheap place to purchase wall warts? Radioshack wall warts don't have enough current and the 13.8v converter is $41.99 plus tax. I know that using the T-Amp with two in ceiling MB Quarts 8" drivers, it sounds pretty good. It seems to lack the base but that could be the configuration of just driving the speakers in open air. Will do a perfect job if i just want to have better sound for watching regular tv.

I wish this thing had a remote. Maybe some modding.....

Ok so I am looking at either a wall wart at 12V 4.5A ($17)

or
Power Supply 13.8 V 5A ($30)

What do you guys think is the best solution for everyday use, like really everyday when I turn on my tv to watch the news and ESPN kinda thing?

Is you're using it to power speakers that you want to use instead of your TV speakers, then go with the wall wart instead of the extra box. Cheaper is better, in this case.

I'd go with the metal box - more likely quieter, more resistent to RF, more likely to operate at rated voltage. You can find one made by "Pyramid" at most online CB equipment sites for about $25.
