Hi. I have a SM power supply that puts out 28 volts and was part of a TEAC Tripath 3-channel (30WPC) amplifier my girlfriend gave to me. I'd like to have a compatible 2-channel Class D amplifier board to put into that chassis that would work well with that voltage.
28 volts is too high for many amplifiers and on the low side for many others.
Does anyone have a good-sounding suggestion or two for me.
I feel sentimental about this kit because it was a gift. I'd love to get it working again!
Thanks for your thoughts on this.

Hi Tabby
the amp is dead?
is there a chance to repair the 3channel Tripath amp? then we need pictures and a small failure "report"
for the 28Vdc the TPA3250 and the TPA3251 are fine candidates.

TI- Texas Instruments you can buy from the shop directly. actually the 50% discount code is not always working.
you do not write about your budget and your speakers(impedance) . is it home use or home cinema? i mean for home use you need not much power for "normal" listening room level. hmome theater configuration or a big room and party mode "request" more power.
maybe a cheap TDA8932 is sufficient?

Another possibility is a TDA7498E based amplifier. Good sound as well. 28V supply is very fine for that chip. It is 28V only and not +/- 28V?
TDA7498E is single supply yes, up to 39V.
TDA8932 runs rather warm when on 28V supply - the quiescent is over 1W. With a heatsink it should be fine though.

Hi. There is no resurrecting the tripath board. So I'm starting fresh. Lower power is Okay. I will either use it for office sound, or the upper end of home theater sound, with an Adam Audio Sub handling the low frequencies (Below 80Hz). I'm a little afraid of a high power amplifier drawing more than this board can handle, though I have beefed-up some of the components on the SMPS. I thank everyone for their responses! I will examine these boards and see how they look & spec. out. I feel encouraged!
28V single voltage, fine.
Be aware that the maximum output power from a class D amplifier is determined by the supply voltage (28V in your case) and the speaker impedance. That means that all the boards we have suggested, that can handle 28V supply, will give the same maximum output power in your speakers. For the sound quality it is for you to choose.

I want passive heat sink cooling rather than mechanical fans being used to cool the chip. I think of noise and motor failure when I think of fans cooling amplifier chips.
Go for one that looks like this one and avoid TDA7498 without the "e".
The fan does not com on, even while playing loud music for hours. it is temperature controlled, but the heat sink does not get even warm.
The sound in stock form is really good and with 8 ohm speakers you will have enough power from your PS.
There are some very problematic boards out there, so better ask before you finaly pull the trigger. Oh, sorry, it is less than 20$.
Spending 200$ will be quite hard and you will not get a return for your money in sound quality. In this case it is OK to go cheap.
