Hi , I have assembled the Titan 2000 kit from elektor and the amplifier seems to work fine at low power levels.When the output power is increased there is a thermal runaway at the output stage. The output resistors stop current sharing.It almost seems that the 0.22 ohm resistors are too small Anybody got an idea? Thank you Torsten
Do you have a schematic ? Post it in alt.binaries.schematics.electronic
0R22 is a common value for emitter Rs in that kind of design. They aid current sharing.Graham
properly mounted on the heatsink.
You think he did something silly like use separate heatsinks for the outputs?

Hi Torsten,
why not ask Elektor drectly, they can be contacted via their Foum, see
hope this helps.
