hello, good morning
by the time here.
Thank you for your answer Joecool85, the amplifier is quite simple: 1st stage with a TL072, between the operational ones, there is a limiter / compressor made up of two BC182 transistors and two 1N4148 diodes, for some cut, then and after the second of the TL072, is the tone control, only with bass and treble and very simple, the tone control output directly attacks the output amplifier in the case of a TDA2050, which is not original, originally had the TDA2030, the power is consisting of a transformer with symmetrical 13.7 volt outputs, rectifier bridge and 2200 micro farad filter capacitors, the whole set is very simple. My goal is to add a reverb line and maybe in the near future change the power transformer, for a higher voltage, in the 2x17 volt range, which would allow to get about 30watts in the output, which is the reference power of the loudspeaker that I have installed a Celestion Tube10, which I recovered from a ZOOM amplifier, after it was replaced by EMINENCE of 75 w.
greetings
