I have a Tascam 564 Portastudio which has a noticeable hum via headphones and monitor out through amplifier and speakers, even when nothing connected to the Tascam except headphones and just powered on but nothing playing.
This was purchased used and the seller is claiming I have it set up wrong or bad mains supply, or that as this is professional equipment it is prone to hum unless used in a recording studio.
Is there a known power supply fault with Tascam Portastudio's in general, or is hum a common problem on these machines?
I have tried it plugged into various mains wall sockets and it always has this mains hum/buzz on the output.
