my old TA-2024 stereo amp

[Dan ʕ•ᴥ•ʔ]

In the early days of Tripath, you could get promo boards, kits and such. Well, in 2006 I built mine. Based on the 2024 chip, it has a miniscule 12 watts per channel @ 0.01 thd into 4 ohms. And oddly enough, that is all it takes to make my 4 ohm speakers happy. So for the time being, I have pulled my TP-60 out of the loop and installed my TA-2024 in its place. I'm using a 5 amp SMPS with it, and I may eventually build a linear power supply. But for now, I'm happy!

Cooool! I cruise with the same amount of watts out of my trusty re-vamped Kenwood integrated KA-2002 with plenty of power to spare
driving my DIY open baffle speakers. Sometimes it seems too simple, but it sounds so nice that it usually disarms my temptations to fiddle with it

Well, foolishly, I listened to people who said that 12 Watts was not enough power for my 89dB acoustic suspension speakers. So, I bought a much larger amp. Guess what? No difference in performance!

My speakers are probably in the 90db's efficient, but the sound quality wins over my need for power. The early single ended solid state
amps, like my little Kenwood seemed to be voiced more similar to the tube stuff that was still holding the top position in the general
home audio world, so I have the similar sound without the fussiness or added attention involved with the tubes. With the new knobs
and humble added side panels, it is the little amp that could

Very nice! Got any pics of the inside?

It was a real mess inside when I got it off of ebay, looked like maybe it had lived next to the fry station in the kitchen. All the wires looked brown and shiny! Took a couple hours with the alcohol and wiping to get the colors to show again. Then re-capped. It sounded kinda dull when first heard it, but the re-capping and up-dating brought back the sparkle. Changed the speaker posts so my spades would fit, and a couple rca's.
It is a nice little amp.

Mine isn't nearly as "busy"... (pic made just before final assembly)

A worthy co-amp is my slightly scratched up Marantz 1090. From a forgotten dust bin on ebay, I re-capped, updated, as a stand alone amp. Added new speaker posts to accommodate larger cable spades. Fed by an updated Superphon Revelation preamp makes a nice trouble free combo. Sitting on top of the Super, I use a freshened up MQ-102 to solidify the bottom of my open baffle speakers at 20 Hz. .

Was this your own design?

 

[Dan ʕ•ᴥ•ʔ]

No, it was based on a Tripath kit.

 

[dfoulk]

Anyone else still using a TA-2022 or TA-2024 Tripath based amp?

What voltage does it run on?

 

[Dan ʕ•ᴥ•ʔ]

12 vdc @ 5 amps

I'm full of questions................what are your speakers that sing with your Tripath? I use these DIY open baffle speakers with my mighty
Kenwood. The top one in an old Heresy cabinet is a Alnico 10 inch Zenith. In the separate bottom cabinet is an unknown Alnico 12 inch
that came out of a GE Vacu-Magic console. Never have been able to discover who actually made the 12 inchers, but they are a nice mellow
sounding, detailed. They are shiny from a couple thin coats of water based poly, an experiment to lower their resonant FS. and slightly
up their QTs. How much, not sure without equipment to measure, but it did improve their clarity and substance, at least to my ears
The speakers live behind screens because they live in kitty territory!
