SL-7 won't power on

Post by cherbette » 05 Nov 2018 21:13

So I purchased a grado mono cart for my Technics SL7 which was causing a great deal of hum. In order to fix the problem, I switched to a DC power supply but did not realize I had the wrong polarity. I continued to use the turntable with the stock AC cord until the correct polarity DC supply arrived. When the correct DC polarity cord arrived, I tested and no power. Now the turntable will not power on with the stock AC cord either. I've disassembled the table to see the fuses but could only find one. I tried to remove the main PCB to see if the other two fuses were underneath but had a hard time trying to remove the thing from the table. I was afraid of breaking it.
