How to obtain better sound out of vintage stereo equipment

By spending $5.00 and replacing the old paper filter capacitors in vintage stereo amplifiers and receivers the quality of sound can be improved drastically. Anyone with basic soldering equipment and knowledge can do this, remove the cover and look for round capacitors that are about an inch long and replace them with metallized film capacitors, these cost about a quarter each and can be purchased on eBay. You won't believe the difference in the sound after this is done.

I'm hoping to improve my car stereo audio quality by filtering the highs and lows. I am wondering if I can use the front door speakers for upper and mid range (> 70 Hz), and the rear door speakers for low range(< 70 Hz). I don't have room for a dedicated subwoofer -- not even an under the seat compact model. I don't sit in the rear seat and other people rarely do, so I don't care if the upper/mid quality is only coming from the front speakers. I have a new receiver (JVC KD-HDR50) which sounds great, which has RCA out options for 'line out' or 'subwoofer out'. I have aftermarket nice front and rear car door speakers (i.e. midrange/woofer). The fronts have built in tweeters, but the rears don't. I also have a modest single channel amplifier that I am using to drive all four speakers at this point. How would I accomplish the wiring for this project? Any reason to not do this?

buy a good brand equalizer or crossover to tweak your system.

HP1020 fax answer phone etc

Digital answer phones record the message on a memory chipset in the same way old tape machines did using a magnetic support. Quality can only be improved by the technology itself, problem is with your specific machine.
If you have a broadband filter try replacing it.
Test the machine on a different phone socket and see if it makes any difference.
Check on your answering machine settings, you should find an option to control volume.

Sibilant output from Pioneer VSX 1018 AH-S

Suspect a DTS board capacitor failures the ESR characteristics.

To troubleshoot connected any available device to RCA stereo connections at input to multi channel in. Test input to the corresponding speaker output confirming audio quality. This circuit bi-passes the DTS function and connects to the power amplifier for the speaker.

Connect any audio amplifier from the preamp out and confirm the quality of the audio.

I suspect that the pre-amp out will contain the distortedf noise. If the distrotion appears in all the channels it is most likely the DTS.

These are repairable.

Hope this helps?
