VINTAGE REALISTIC STA-20 DEOXIT CLEANING & SERVICE RECEIVER AMPLIFIER HIFI REPAIR FIXING RADIO AMP

deoxit pot cleaning and service vintage realistic sta-20 receiver amplifier from 1975 so in this one im taking the face plate off to check its all look ok behind it and to give it a clean as the back of the glass looks very dirty and then i will be cleaning all the pots and switches with a can of deoxit because i doubt this old vintage realistic has had a good service in years
