The TDA7293mod uses two TDA7293, one as the Master while the other is a Slave. In the Slave unit, only the power mosfets are used. This is equivalent to doubling the power mosfets of the Master. Because of that, the TDA7293 modular is capable of higher power output, particularly into 4 Ω.

1kHz Full Power into 4 Ω
10kHz Square Wave into 4 Ω

The TDA7293mod is one channel and is supplied Unassembled. Two kits are required for stereo.

To complete the amplifier, the following are needed
1) a power supply consisting of a power transformer, filter capacitors and a bridge rectifier
2) a heatsink for the power mosfets
3) a metal case and the necessary connectors
