Is he old? At one time some amps could be connected to the head on a tape
deck - so that input had high gain and equalization. A bit like a pickup
input.
But these days an input labelled tape is just an ordinary line input and
likely identical to one labelled CD.

1. Give him his money back. In the end, no matter what you say, it's going
to be the best solution. Far better than trying to convince him you
are right, even though IMHO you are.

2. You can find a descripton of the unit on the lower left corner of page 15
of the 1988 catalog. http://www.radioshackcatalogs.com/catalogs/1988_small/

I infer from what it says that it has a line level input for tape. It says
"Function switch for FM Auto, AM, phono and tape. IMHO that implies a
LINE LEVEL input which can be used for a tape player or CD player.

In order to use it, he has to connect the LINE LEVEL output of the CD player
to the TAPE IN. There may be a TAPE OUT on the back, he should ignore it.
Then he should set the function switch to TAPE and be able to hear what
he wants.

Looking at the picture, there is a TAPE IN jack on the front panel over
the PHONES jack, he should use that. There is no picture of the back in
the catalog, nor does Radio Shack have an online manual.

If he does not hear anything, he should try the FM or AM settings with an
appropriate antenna. If he hears nothing, then his setup is probably wrong.

If he only has an earphone jack on the CD player, he is trying to force it
to do something it was not designed to do. He can do it by setting the volume
control on the Radio Shack unit to a comfortable level using the AM or FM
tuner, set the CD player to minimum volume and play a CD, then he should
adjust the volume control on the CD player until he hears what he wants.

Then he should mark the spot on the volume control and remember to put it
back there BEFORE he tries to use it with the amp.

I would not return the guy's money. He'll probably give you negative
feedback anyway.

By the way... On at least two occasions where eBay sellers returned my money
because the product was defective or mis-described, I left positive feedback
stating that I was pleased with the transaction, because I'd been treated
well. Unless you expect a similar reaction from this guy, don't return his
money.

Yea, he's plugging into the low impedence headphones jack, as the
cheap portable chinese made CD player he has doesn't have line out.

The radio/receiver would make no difference at all. But he might try
the phono input that may be a lower level input.

Or tell him to buy a real CD player?

Hold on a second, here.

Any "Walk-device" headphone jack should be able to put out at least half a
volt, more than enough to drive just about any amplifier. It merely requires
turning up the volume. A true line output isn't needed (though it would
probably provide better sound).

Furthermore, the phono input on this receiver is for magnetic pickups. * The
output of even a headphone jack will drive it into distortion -- not to
mention having the signal's bass boosted and treble rolled off.

* The manual says that a turntable with a ceramic pickup should be plugged
into CD/Tape.
