Technics SA-5550 anti-shock timing circuit
1976 Technics SA-5550 stereo receiver was working perfectly. But then I used air blaster on it to clear out dust, and the the “anti-shock timing circuit” stopped functioning. The literature on this describes the anti-shock timing circuit as “helps eliminate annoying thumps in the speaker after turn-on by delaying turn-on of the speaker terminals”. What is the remedy? Is it possible dust got lodged in the circuit?
