Williams Audio Tripath Ta 2022 Amplifier.

[Ali Tait]

This was built by Duncan (Tubehunter). It's a Tripath design using two TA2022 - EB evaluation boards. Each board is a stereo amp giving around 90 W/Ch. Each board is bridged, giving about 200 watts per channel.

Spec-

2 300VA mains transformers
2 10,000uF 100v first stage caps, followed by 4 10,000uF 100v caps in a crc network a la Nelson Pass.
2 35amp bridge rectifiers
Custom made very quiet regulated 5v supply for the Tripath input stage.

Mains switch is on one side, the RCA inputs on the other. Speaker posts on the back as usual. As you can see from the photos, the power supply and output stages are kept separate.The output stage side is copper clad top and bottom.Great design and a great sound.

I'll sell for what I paid-£200 plus postage, which might be a few quid as it's pretty heavy.

The marks on the top are from sticky pads I had stuck on it.There are a few minor scrapes etc. but nothing major.I'll see if I can clean them off. It's been sat in the cupboard for months, so I'll fire it up and make sure it's working fine before dispatch.
