Loud him in mine was a bad 40 MF section of main power supply dual filter capacitor. Antique Electronics has a CE Manufacturing 40/20/20 MF, 500v can that will work fine. You will need to drill additional hole in circuit board, but it fits fine. It is 2 1/2" tall. Original is 2" tall. New one fits fine.
What might cause LOUD hum in a Conrad Johnson pv6
The PV6 today blared out a loud hum after it had been running fine for a couple of hours. I shut off all power to the amp, pre-amp, tuner etc. I noticed when I moved the preamp that one of the output cables was disconnected.
I don't know if it somehow disconnected and it caused a hum or became disconnected when I moved the pre-amp. In anycase, I later plugged the cables back in securely and used only a tuner STILL A HUM then a turntable and STILL A HUM.
I am looking for someone who might have an idea what is causing the hum. I opened the preamp No smell all tubes appear to be working. So I am puzzled.
