Default electrocompaniet ec 4.7

Hi I have a preamplificaor Electrocompaniet EC 4.7 I to buy second hand and I see several things that a burning track is negative balanced output, another is that by injecting a signal generator cut out only the dc input and the variable resistors have not been touched and that values
Deven have to stress or are regulated
Someone would have on service manual-thanks-Michael
