Allegro preamplifier by Dr. Borivoje Jagodic
I am writing this to contribute and inform DIY community about another
design by Dr. Bora Jagodic.It is about his preamplifier design named
"Allegro" that has been built and tested by me. This days I've finished preamplifier Allegro according
to schematics from Borivoje Jagodic. You can find that schematic on his
Here is how it looks today:
DIRECT mode-----no limit
BYPASS mode----10Hz-108KHz ( -1dB)
TONE mode ------14Hz-87.5KHz (1dB; control "flat")
> THD (20KHz 1V rms output)
DIRECT mode---- not measured
TONE mode ------<0.0026%
> TONE CONTROL
BAS----------------±12dB on 50Hz
TREBLE----------- ±12dB on 10KHz
DIRECT mode------ not measured
TONE mode --------100dB (or best)
Pa mislim sta reci!
