<div>As written in the dev list, the problem is with the transistors: </div>

<div>It was not easy to find any details, but it was mentioned something about a fix:<br><br>

<p><em>I don't know if there will be any easily visible labels or such. I<br>know it's printed quite clearly on the PCB </em></p>

<div>It sounds to me as the problem is easy for those of us that knows a little electronics. If I get one that leaks current, I will start soldering!</div>
<div>
<p>Does anybody know if the fix Werner is talking about, will be done for all GTA02v5 PCB's? If it really will be a fix for it, it will not be any problem at all.<br><br>-- <br>Please don't send me Word or PowerPoint attachments.
