Ok, pretty sick of having these guys around. 510: Great shape minus not having a backplate and some minor scratches/wear. Had it repaired a few years ago by Chris at dB-r and he did a great job. Previously bought it from USS Enterprise at DIYMA with some issues. Cosmetics 7.5/10, mechanically 10/10
505: cosmetically, give it a 5/10. Mechanically a 9/10 because of gain issue explained below.
Anyway, sound great - just have no use for them. Moved out of car audio and into home audio.
100x2 @ 4 ohm
150x2 @ 2 ohm
300x1 @ 4 ohm bridged
underrated by some amount, not exactly sure how much.
Pics: 510 is obviously the bigger amp. The smaller one is the 505. 505 is dirtier cosmetically and has an issue with the gains making a scratching noise through speaker output when you adjust them but sounds perfectly fine when it's running normally.
$90, includes pp fees AND shipping - for the 510.
$50 including pp fees/shipping for the 505.
