Two TPA3255 Amplifiers HiFi Builds

DrMordor...

Seriously.

You have AC 110vAC input power supply with super sonic fast switching rectifier with graphene doped capacitor bank rated for 48-51VDC continuous 1200W output?

😀

Sorry bro, only with diamond finishing)))))

If it were me, I'd Email this company and ask them what caps (C1 to C8) are used plus what Op Amps are used. Upgraded caps are most likely wanted.

Also I'd ask them to install Dip-8 sockets so that you can roll Op Amps in the future.

I've reached out to them about 4 times by email and a form on their WEB site. They appear to be out of business. I can't get a hold of them at all.

I read about a person named Tom that is involved with the company. Wish I could get hold of them. I thought about driving out to their business address to see if they are open. Not too far from where I live.

I really want to find more information about their TPA3255. Looks like a full feature set design of Ti but with some possible benefit tweaks... Not sure.

I may just order it and see if they ship it to me.

I'm going to start with just 1 TPA3255 for now.

After all my research I should be able to dial in 2x8ohm speakers rated for 100W each with just one well designed TPA3255 amplifier.

L and R HI-FI 100W x 2 load of speakers should keep me happy the rest of my life. 😀

3e has a mono tpa3255 board.

I would rather ask drmordor to sent me 2 of his boards modified for mono operation.

The docs will do mono but have my own power supply.

No problem,
Akita "AllInOne" Amp based on TPA325x PFFB+ and LLC PSU in one board.

I have some solderless boards.
I can solder you.
One problem, a quiet pop when turned on.
