TDA7293mod
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.

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
