scottly you forgot the awesome sansui (sansoooweet) amps, they are as cool as our Webers...

[scottly]

Yeah Frank, I also forgot about Mackintosh.   Speaking of Sansui, I have a Sansui Six receiver down at my shop, that is connected to a Kenwood KR-5600 receiver, to give me independent volume controls for the machine area and the main area. I bought the Six at a yard sale for $20 bucks or so, and it came with the manual, which included schematics! I also have a Sansui 5000A, but I'm not currently using it.
In the early '70's, a Sansui amp came into my dad's shop for repair. The right channel would intermittently fade out, sometimes blowing a speaker fuse. One time, with the unit cooking on the bench with a low wattage test speaker, we were finally able to catch the failure in action: the sound faded out, as the speaker cone slowly retracted, then the voice coil melted!
These amps were directly coupled to the speakers, with a +/- 34V DC supply. The drivers would fail, and force the output transistors into full conduction, which fried our test speaker. It turned out that Sansui had already corrected the problem with improved driver boards, but the replacements cost something like $50 each.

If you are running anything that old scottly at the bare minimum you would need to recap the power supply capacitors and probably the power supply diodes to be on the safe side.

You know you need to replace the power supply caps when you can hear the 60 cycle hum. If it ain't broke, don't fix it.

My Sansui reciever has been delegated to doling out tunes in the garage while I work on SOHC's!

You can always check the classifieds section of ww.audiogon.com for prices on stereo equipment. Often times, I find them to more accurate than eBay pricing.

 So, I thought I could run the wires from the "to speakers" connections to the Klipsch monitors and use them with the sub, since it has it's own amplifier. But, when I do that I only get the bass.



 Is there a way to keep and use those three (with input from my phone/laptop/Sirius boombox) and get music? Or do I need an external amp or receiver?
 I know the Onkyo amp needs a pre-amp and/or receiver with pre-amp outputs.

Like I said before you should be able to run the speaker wire from a receiver to the from amp and get bass through the sub (looks like the level controls are on the front) and the higher frequency signals will be passed on to the satellite speakers (the small klipsch) from the to speakers.

It sounds like you tried to hook your laptop directly to the sub, it won't work that way. You would have to hook the laptop (source) up to the receiver via an RCA input.

Google up the user manual. It will explain how to hook it up.
