The ori version of TDA2050 has been discont...on 2012..Right now only the clone of TDA2050 on the market...This clone version 25W only..The ic protection not guaranteed 100% work.3A max...nomore 32W TDA2050 now...

For the price...on my country...TDA2040 $12.50 .... TDA2050 clone only $7.45..

TDA2040 more stable on low voltage .
