Time for a cooler amp...

S Clark · July 03, 2024, 05:44:31 PM

Usually in June or early July it's time to move the tube amps to the storage shed and put in something cooler. It's been in the 104 range for several days, and anything to reduce heat in the house is welcome. And when the 107-110 days come (and they're coming soon), you just have to stay in and hide from it.
So I've been listening to my little TDA 7297 Folsom amp... and it's really good. I've got some cables to review, so I've got to let it settle in, but I'd kinda forgotten just how detailed it is. It certainly can run with the big boys as far as sound.

Jeremy, is there a chance that you'll ever run another batch of those boards?

Yeah, that 7297 amp is really special. The one I built and sent to Danny started a thing and it ended up in the hands of John S. who has a pair of Super V's. Evidently it kicked an expensive, much revered amplifier's ass.

Didn't Jeremy do another amp as well? I read all the great comments over at AC.

Folsom · July 04, 2024, 01:03:14 PM

Yes I did. And it is better in every way.

That's what I thought. But some of the components are no longer available?

Folsom · July 04, 2024, 02:35:08 PM

I don't know what they are so that is news to me.

You lost me on your response. The other is a chip amp with board and some miscellaneous parts, right?

I disavow any knowledge of out of stock parts. The closest thing to that is having to order one regulator from newark, as far as I know. On occasion you order a part from Digikey or Mouser if the other does not have it temporarily. This is as ordinary as breathing at this point. So saying there are parts you cannot get does not mean anything to me other than nonsense claims.

No. There is nothing misc about it. It has a discrete front end that controls the output devices that are chips.

My friend Brad has the higher power 7293 amp almost finished. I'll report on it when it is finished.

Ok. Thought I'd read a couple of years ago on another site(s) that one or more parts weren't available. That's about all I can remember......

That will be fun to hear his opinion.

Dave,

Any idea if Brad ever finished that 7293 amp?

Nope. I'm in Texas and will be home Monday.

I'll email him and ask. I REALLY want to hear it. Jeremy's 7297 amp is a low wattage killer.

I have had all of the parts to build a completely new design by Jeremy. I've had it for way too long. This has been a terrible year physically, but things are looking up. My arthritis has plateaued and I found a new therapist, so my hands are beginning to work again. I really, really do want to do this build. 👍🏼

I love the recreation of great music.

Glad you are turning the corner physically. I am set for a one level fusion in my low back in July.

I think you also had a dac build planned using multiples of the TDA 1543 chip.

Praying for better health for you 🙏
