ok .....
case :hardman cardon AVR20II
symptom : having a baby ...... at home .... resulting half a glass of coke inside the amp while operating ( !!!!!!! )
only outs , drivers , a few resistors and a few caps .... nothing that can not be faced in any normal lab
though A1859A and C4883A drivers do not exist in the greek market so i replaced them with mje 15033-32 and the extreme semiconductor 2sc 4137 was repalced with a bd 135 .....
finally a resistor network of 10 R and 442 R that was responsible for seting the bias was replaced with a 390R resistor and 100R multiturn .....to be able to set the bias propely
amp is working just fine any comments ???
thank you
