That is why you let the Japanese handle the electrical systems.
I still have the following items all made by Panasonic:
AM/FM Clock radio made in 1980
AM/FM Stereo with eight track and Thrusters speakers made in 1977
My first flatscreen 42” Plasma TV bought at Sears
You can’t kill Japanese-made electronics made in the 70’s/80’s/90’s . I have a top end Trio ( Marantz ) turntable made in 1975 that still works like a champ . All I’ve done is replace the stylus regularly , My Onkyo amp/receiver was bought in 1995 and I’ve never had a problem with it . Before the Onkyo I had a Pioneer amp/receiver which I sadly had to sell to a Japanese friend before moving back to the USA for 6 months in 1995 ( when I bought the Onkyo ) . It was bought in 1981 and she is still using it !
