Pioneer C-91 Preamplifier :
$474.95
I took this to my tech because of a background hiss in the audio. He replaced all the relays along with other repairs and it sounded clear on his bench. I took it home and played it on several different amps but the hiss noise is still there, especially when the tone button is engaged. I’ve replaced the C-91 with another so I’ve given up on this one. It’s in good physical condition except for a nick on the side panel.
