Hello everybody.
I assembled the ''sixties-style 40W a. amplifier'' (Elektor 7/8-2011) in a stereo version, using the TIP3055 transistors.
Everything looks O.k. but:
The F1 (inlet protective) fuse is always burnt out, or
The resistor R11 (100R) is totally burnt at once.
When i replace the fuse with a 47R/5W resistor, it is also burnt out at once.
I checked the transistors, and replaced T2 (BD139) but the same problem occurs.
Can anybody help me find a solution?
Thank you and wish a happy new year.
