Mystery Classe DAC1

KnyazHM · 02:17 PM

Hi,
Tried to listen to him, did not go perfectly. But before you put the donor on the table, decided to take a closer look, modes compete. It was found that the quiescent current output buffer is less than miliampera (!) In all four channels (DACs fully balanced), moreover, how to put it something more was not possible. Instead of R517 (or similar) size 274oma according to the manual payment simply soldered jumpers. Established the 470th, exhibited a quiescent current of about 30mA. Sang! That such "upgrade". Engineers Classe I did not understand, but for the owners of this DAC, I hope this can be useful information.
