I got this working with the MJE3055T. The pin out is different and I had to solder leads and shrinkwrap. I used 26 gauge solid core because thats all I had but 20 gauge stranded would be ideal. The collector pin has to be isolated with plastic shoulders. I get 55 watts before clipping. Im...
The schematic is hard to read. The schematic shows 85mA near this part (Maybe signifying the overload current that trips the fuse?) If this is true then the power dissaption according to ohms calculator would be 0.4913 watts. Therefore I used 68 ohm 1/2 watt fusible resistor. Mouser number...
Replace TR721 and TR722 with MJE15031G and their complements TR719 and TR720 with MJE15030G
And listen to avionic he knows more than most people in this forum and has helped me through several projects.
Looking at your pics all the resistor values look good. Make sure to check the resistor covered in cloth 4.7ohm. Ill post a pic of the traces of Tr722. The wire that was on the collector of TR722 to TR708 must have been on the heat sink of TR708. Not sure why they did that. Even if the trace is...
