Old turntable works but is too quiet to hear

maybe the internal fuse for sound output section has blown?

make sure your volume to your headphones on your mix board is turned up.

I can't find either model you mention anywhere but a turntable without a built-in PHONO preamp will require an external on to drive any input not marked explicitly for PHONO.

eBay always has some...

If you're using an old-school turntable that doesn't contain a phono preamp that will happen.

A traditional turntable requires a Phono preamp inline with it to PRE amplify and frequency-balance the minute signal produced by it's cartridge for later amplification by a power amp. Most stereo receivers and preamps have Phono connections and internal preamplification strictly for that purpose.

Recent AV Receivers generally do not.

The result would be very low, tinny sound.

If so, you need to get an external Phono Preamplifier.

Some modern TT

The output from any regular turntable is far too low for most amplifiers to handle. You need to either run the output through a pre-amplifier first to bring the signal up to line output levels suitable for most recording devices and amplifiers or run it into an integrated amplifier which includes the pre-amp stage.

If your Bose receiver specifically includes a turntable input then it has a pre-amp built in, but as so few folks use turntables any more very few devices have the correct input. Pre-amps are still easy to obtain and can be very cheap, but cheap ones produce a noisy and unpleasant output which is magnified by the amplifier. If ever there's a choice to be made, spend the money on the pre-amp and go budget on the main amp.

I hope that I've saved you wasting money on something you didn't need. Please take a moment to rate my free answer.

Are you feeding the signal into the PHONO input? If not, then the volume will be very low. Make sur it is a PHONO input, not all receivers have them now.

There will be some feedback from the turntable, and this is totally normal. Ive actually heard the music from the needle itself, and is nothing to worry about

I have the same problem

it sounds like you have the polarity of the speakers hooked up wrong on one of them, try unhooking the new speakers you added and hook them back up one by one, when the music gets fuzzy then reverse the wires for that speaker, this should cure your problem.

Unless you have a choice of inputs, nothing.
If available, you can try a magnetic cartridge input which is much more sensitive than 'Line.'
It may be screechy though, different curve.
