hello ,
i need to find a replacement for an ac151 r VI transistor.Does anyone know which transistor should i use and where to find it ?
This transistor will work in the motor board of a uher 4000 report L reel to reel.
thank you.

An AC128 or even an OC81 should be OK, but it's difficult to be certain without seeing the circuit.

I have the schematic that shows three AC151 VII transistors.In my uher there are three of Ac151 r VI.Both of them are difficult to find.So,please any suggestion ?

They are just small variants of the AC151. Use an AC128.
