For anyone that thinks they may be replacing the transistor more than once, you can cut single sections off of? SIP sockets and solder them onto the pads. Then? it is as simple as unplugging one transistor and plugging in another without the worry of lifting pads.

Hi Allison, thank you for the comments. Luckily enough, R84 was not altered as I found full 12V on transistor collector. At the end, an old TO5 metal-case BC142 came out of my "marine" junk box so I installed it immediately. Needless to say, now the ubitx puts out its full power and works as it should. The precise indications by the Group have been fully effective. Given the BC142 is a robust transistor and that now I know I could eventually replace it at once, I will not install protection diodes: You are certainly right. Bests, Jep
