20W TDA2005 Poweramp

I understand the power supply would need some serious current carrying capabilities, but paired with the right pre amp this could be a fun project. Also, splitting your signal into two different pre-amps and sending it through as a stereo signal would be an even more fun project.

The chips can be had cheap. would need large heat sinks, but if (like me) you have a capable power supply in your garage, it could be worth a build. I noticed that this site doesn't have any power amps with this much power.

Thoughts?

I love these boards. They sound great paired with a preamp. No heatsink required.

I'm going to buy one of these. I think you've already bought one so what is the "mute" connection? Is it something like a connection for a volume pot?

Holy crap, you've opened up an entire new world to me. Thank you.

If I were to go larger and use something like this:

Would it be necessary to add a choke after the transformer. I'm uneasy about this one, sending the AC directly to the board, but the possibility of the high power I'm loving. Plus I have the perfect power transformer kicking around out of an old Peavey amp.

also the stereo feature is pretty important to me.

You wouldn't use a choke to supply this with AC. The eBay description says 12-36VAC

Hey Rock, happy to help!Edo, not sure about the mute pads, I've never used it. I just left them as they are. Probably use a switch there if you want the ability to mute.

Hi, i've built the tda7375 and the mute/std by connects to +vcc.

Hi, i took the tda7375 (30W) and built the double bridge circuit http://www.datasheetcatalog.com/datasheets_pdf/T/D/A/7/TDA7375.shtml

the power supply is 4*18650 battery in series (16-14volt), both inputs connect to the output of a RC booster pedal and i have a portable amp!!!! very easy and few components ;)

it doesnt play louder than drums, but plays jazz and such styles that don't demand high db.
