Cigarette Smoke Harm Solid State Unit ?


I rescued an older Marantz receiver . The interior is covered with cigarette tar . Do I need to clean off any particular components or should I leave it be . This is a working unit worth $1,000 cleaned up . 10Q

Let me tell you a short story. I have an Uncle who is slightly crazy(been in and out of an institution several times) and he got the great idea of heating his house with candles. We both live in the north east US it tends to get cold here in winter, well the summer before the test he began buying candles by the gross. Half way through the winter he had to replace his computer, his audio reciever and his wireless doorbell among other little electornic devices. He discovered it is cheaper to buy heating oil. Bottom line soot=short elctronic life.
Darn, so much for using the smoke house, out back, for my dedicated listening room.
Well Dekay, you might not have your electronics for long, but at least you wouldn't have to go far for some good "eats" while you're listening : ) Sean

Yo Fbi, The components that usually require a thorough cleaning are the ones with moving parts...potentiometers, variable capacitors, relays, and switches. To do a complete and thorough job will require complete disassembly of all circuit boards from the chassis. Then the parts can be cleaned spray contact cleaner and lubricated. The circuit board(s) should be cleaned with alcohol and allowed to dry. The cleaned parts should then be checked for spec with a VOM or a capacitance meter. Then before you reassemble the unit, clean the inside of case, the tuning dial/front panel displays with alcohol or windex. With luck you should be able to reassemble the unit and get it working but it might require a realignment of the FM tuner section. Good luck.
