[Premium-Rx] Siemens chip info needed

[Karl-Arne Markström]

Hello, 

The TBA120 would be a suitable replacement,
data sheet is found at:

http://f5ad.free.fr/Docs_Composants/TBA120.zip

The SO41P can be bought for 14,90 € apiece from
Barend Henriksen HF Electronics in Holland (Barend Henriksen have my full recommendations as a supplier).
