Hi good morning, how's it go this morning? With me it can go well, if I short out my amplifier and get it work like I wanted to be. I attach some pictures to show you how it looks. If you can see the left side of the 2sc5200, they not warming up like the right side of the 2sa1943 transistors. When I power it up with dc +55v -55v the right side of the 2sa1943 transistor the first transistor from your left side getting very hot and burn out. I build it exactly from the schematic like it is. But but still getting the same problem with it.

B100 & B500 TEF

Thanks APEX, this is my second B100, and Driver B500 TEF the first time I've made, I want to use the 8 pairs toshiba, how many volts do I need for the maximum and minimum Ampere Transformer? how many watts I get to 8 pairs of Toshiba?

Sound is get very clear and very nice, power is one of my favorites.

greetings. Damanhuri

For 8 pairs use 1200VA transformer 2X80vac maximum.
