T3 monoblocks
Just finished and only tested on small metal test speakers. No real idea how they sound except to say they work. Appears to be no hum or otherwise, always a good start. Even thought you buy the modules fully assembled build time is high. I spent most of the day just completing them after already spending a lot of hours on the back plate.
Bits and pieces; The Tripath modules are the T3 150W monoblocks. The gate controller chip proudly displays the Tripath name. The modules are quite small and cut down. No mechanical speaker protection, only small electro on board and not a lot of parts. Could be a sign of better things to come. The tranni is a 300VAC 30-0-30 and I paralleled the secondaries. That provides 30VAC @ 10A. Rectification is by a 10A rec. bridge which is soldered directly onto the first cap to ensure maximum current transfer to that cap. The secondaries are soldered directly to the rec, bridge. A 0.1uf poly bypasses the first cap to reduce bridge and cap noise. And as usual it has its onw mains EMIRFI filter.
The caps are 2X Mundorf MLytic 22,000uf 63V (44,000uf per monoblock). They are ultra low ESR audio grade and cost $60 each a total of four is required. I wanted to use the 47,000uf high current versions but I couldn't fit them in the case. Power wiring is via thick speaker wire and wiring to extra heavy duty speaker binding posts is very thick speaker wire and is quite short.
Connection to the board is by large brass spades so a board replacement is an easy job. RCAs are solid copper, palladium and Teflon. The enclosure is steel with a nice finish. Only four large screws hold the enclosure together as a lot of it "clicks" together. Speaker binding post are two way, are insulated and solid brass, big and heavy but nice!! The PS will deliver 420W and the amp can deliver 300W into 4ohms or 150W into 8ohm with 300W peaks. I called the monoblocks "Tutu" (think Mola Mola)

- I like your design choices. Received my t3s a couple of weeks ago. Will be assembling the components next weekend. I like those jaycar boxes. Good value too.
