Post Re: Roberts RT7 - problem

I can't see the metal clip, but for this radio if it is used at average listening it is unlikely that the transistors will need any heat sinking. Whilst it is desirable most small output stages just have the transistors without a heatsink as not much heat is being produced. It may be possible to remove the plastic cover though I have never tried this, and the markings would be lost of course. A suitable replacement transistor which is more robust would have been the AC128.
