OTGW - Components

Post by dirkmans »

Hello,

I was searching my components for a BC558b transistor, but I can't find any.
Next I looked at the conrad site, and there I found out that it is not available anymore.
Can someone tell me which one I can use as a replacement type?

I expect no problems if you use BC557B's or BC556B's instead. They have a slightly smaller bandwidth, but still plenty for the low frequencies used in the OTGW.
