2 Piece TDA2030A output power transistors connecting the power upgraded 200w amp circuit We all know I think this circuit, the first in 2000 Elektor I saw it in a long thin pcb printed circuit drawings had worked fine had in fact circuit the purpose of making my hand on my transformer was to evaluate the circuit from a single source because it runs my business had arrived circuit 12v … .36 v between supply and can run, but 12v and the efficiency is not good work best 24v …. 36v from happening suggestion at least 20v power use ..
Anyway, let’s get a new printed circuit event this circuit to do it again decided , but first I made PCBs now my eye to look nice did not :) on the internet a bit some research to have done much more in a drawing found , but these drawings used in the transistors of the leg links of non-standard ( bd508 , bd705 ) base and emitter in the opposite direction also drawing some departments did not like me again printed circuit drew new drawing was more orderly in addition to input and output supply and speaker make out the clamps on the output line fuses ‘ve added a smaller size was
As I said, I did not get 12v to 24v with a yield tests worked fine for power transistors TIP35C, I used tip36c bd249 bd250 used instead.
