I have a Seeburg Disco that I'm converting to a virtual jukebox. I have a complete working pc setup with a nice 19" touchscreen monitor. How do I hook up the pc audio output to the Seeburg amp and speakers?

Good question. I've always seen those virtual jukebox forums (like over on BYOAC) mention using a car audio amplifier. Don't know if that means I can use the original field-effect speakers, or whether I need new ones.

If I can use the original amp with the great quality I hope for, that would be better.

Mine is a Rockola 450. I already have the touchscreen, software and PC setup. Need to figure out how to mount the touchscreen in the top (probably need new glass cut), then figure out how to amp the music like you're trying to figure out...

If you want to use the original amplifier, and go through the turntable inputs, I would think you need to simulate the RIAA equalization used on vinyl to make it sound right.

You can read about RIAA equalization on vinyl here: http://en.wikipedia.org/wiki/RIAA_equalization

But here is the gist of it:

RIAA equalization is a form of preemphasis on recording, and deemphasis on playback. A record is cut with the low frequencies reduced and the high frequencies boosted, and on playback the opposite occurs. The result is a flat frequency response, but with noise such as hiss and clicks arising from the surface of the medium itself much attenuated. The other main benefit of the system is that low frequencies, which would otherwise cause the cutter to make large excursions when cutting a groove, are much reduced, so grooves are smaller and more can fit into a given surface area, yielding longer playback times. This also has the benefit of eliminating physical stresses on the playback stylus which might otherwise be hard to cope with, or cause unpleasant distortion.

Here is the hardware solution:

Seems like there should be a software solution as well...
