I built this board this summer but haven't used the remote feature until now. When I tried I found that I mounted the motor driver, BA6418N, backwards (clumsy...). When I tried to remove it, two legs from the IC broke (inside the IC) so I cannot use it any more.

Does anyone know where to buy a replacement part in the EU. It doesn't seem to be in stock at any of the distributors I have used (elfa.se, farnell, mouser,...). Veteran: you do not happen to have a spare one that I can buy?

This is my new preamplifier which I'm testing (I'll use it in this project). Seems promising

Veteran,

What are the differences between this new preamp board and your old board? Are the new boards available yet? I would love to make a set and plug them in to compare the two.
