We only have this amp with MCAP's now. See here.
The T3S is the new stereo version of T3. It has two sta517b output stage chips and are good at driving 4 ohm loads. 8 ohms loads can also be handled, but the T4 amp will produce higher output for 8 ohm loads.
It is similar to the T2 amp except higher powered and that it doesn't have a volume pot.
*300W+300W output @4ohm, 150W+150w @8ohm
*Power requirement: dual ac 34 - 0 - 34 or single DC 48 - 0 (AC between 30 to 36V is ok, and DC between 36 and 48V)
*Input impedance 20K
*Input sensitivity for full power 1.5V
*Inputs: 2.54mm connectors for signal, 7.62mm connector for power supply
*Outputs: 7.62mm connectors
*Speaker protection: DC/error and power on delay, power down immediately off (when transformer powered)
*Power down interface to switch or controller: It can be remotely switched off from compatible preamp or controller. Shorting the 2 pads of the power down interface will power down the amp.
