"Quiet Strom (take II)" - `100W Class D Tripath amplifier

 










This amp has been put together from most parts on hand. The enclosure once held SS amp and has a good PS including 20,000uf of smoothing caps. The T4 module has a further 10,000uf Nichicon filter cap onboard. This amp module is a T4 Tripath module and with an appropriate tranni will deliver 180Wpc. The PS will deliver 100W and with even low efficiency speakers will play loud.

The smart looking two tone enclosure is steel and Al. The IEC socket also has a RFI/EMI power filter. It is fused (internal) and earthed. Silver plated wire-warp wire is used in the signal path. The amp is dead silent with music off and is highly detailed. Bass is deep and extended and very well controlled. Very good use of parts which have been unused for so long.
