Does anyone have any spec. on the MJ15032 and MJ15033 ? I'm building a tubeshunter NAP-140c kit which claims to be based on the Naim circuit. The kit came this TIP41C/42C drivers in place of the above but I can't trace a data sheet to see if they are suitable. In fact most of the semis are not are the PCB markings. Has anyone had a go at this kit?
