DIY amplifier TDA2040 2x25w rev.1

przedwzmak z elizabeth, koncowka gotowy kit na tda2040, zasilacz seasonic chyba 200w, pierwsza moja konstrukcja, na razie ehst srednio, z uwagi na zasilacz, b.słaba linia -12(do koncowki potzrebny zasilacz symetryczny) mase "smieci" slycjhac w glosniku np krecenie wiatraczka odbija sie w głośniku.... poza tym potzreba 18v, mysle ze jak zbuduje zasilacz symetryczny 18v to bedzie lepiej, ale jak narazie wazne ze gra:)

what kind of equalizer is that?

[tanx90]

It was taken from old polish amplituner Unitra Elizabeth Hi-Fi. It's for 18 volts so it was perfect:)

Fajny wzmak z ATX bedzie z 10W a nie 2x25W :)

[tanx90]

nom, ale to jest podana moc nominalna kostek wzmaka, a w opisie jest podane, że wzmak przejściowo zasilany z zasilacza ATX:)

stuped song!

[homen2010]

clever

[jwish29]

could you post a schematic for us who would like to build this?

[bob505470]

@Sub40H true, but it is extremely hard to make a transistor to ad in those harmonics and coloration, many have tried and failed

[mmarti944]

Noo :) niezły ;] całkiem nieźle daje basem jak na takie maleństwo :]

Skąd mówisz wyciągnąłeś tego preampa ? :)

Pozdro! masz plusika!

[Sub40H]

@bob505470: That coloration is usually harmonics & frequency resp distortion which can be added by a "deliberately ill-designed" transistor amp as I said.

[bob505470]

@Sub40H well, technically transistors are better at reproducing a perfectly accurate signal, but tube amps and a sort of coloration, but thats not necessarily bad because tis usualy sounds better to the ear.

[Sub40H]

Why do a lot of people still say Tube amplifiers sound better? Its theoretically impossible unless the transistor amplifier is deliberately ill-designed.

[bob505470]

now build a vacuum tube amp!! they sound even better! if you got the money that is

[CassetteMaster]

AWESOME! Very nice sound.
