Tripath TA2020 4 Channel Amp
This was my first foray into Tripaths (after the Sonic Impact mod)
I found an individual who was working for a Video Game Kiosk company that were test prototyping 6 channel Tripath TA2020 amp boards . He had about 20 of these six channel amp boards and I bought quite a few of them. This particular board had two channels in protect mode (1/2 output) and I used the working 4 channels to build this amp. Sound has that Tripath sound and the TA2020 is a 20wpc. Could use a few more mods. I have installed a LM350 Voltage reg to bring the 19VDC 3.2A Laptop Power Supply to a usable 13VDC. The LM350 allows up to 5A, while the lesser LM317 was limited to 1.5A. Has a pop upon startup and pop on shutdown due to the 10,000uF cap installed on the power leads to the board. All encased in a nice Hammond enclosure - bottom of enclosure is a bit hacked up from a previous botched job. Anyway, $85 plus shipping takes her...

I had to take this posting off the trading post a year ago as I had to move across the country.
Anyway, it is again available...
