    Sansui sp 2000 - should I add brake fluid?!

    I just picked up a set of SP-2500's on marketplace. Virtually little to no bass as the surrounds were stiff as a board. removed the grills and laid them on their backs. Carefully applied the dot 3 to the fronts of the surrounds only. With my thumbs lightly began to push evenly on the cones and...

    Vintage Sansui speaker guidance please - the good, the bad, the ugly?

    The AS-100,200's, 300's are worth getting. They are sealed boxes and have the same sound signatures as other sealed boxes of the day such as Advent, KLH, AR etc. As with the SP line surrounds are cloth but generally have stiffened up over time. A lite coat of DOT3 seems to do the trick. The AS...

    KLH 5 Replacement Woofer? correct?

    The positive of having the replacement woofer is that you can use it as a "big" bargaining chip on his asking price...whatever it is.... using the other info on the thread as your chips. Fun speakers to own and restore...lot's of info available here on AK. Good luck!

    Realistic Optimus 1 crossover mod to increase HF response ?

    Been a while since I put that post up and I no longer have the optimus 1's. If i remember correctly the the optimus 1 woofers screw into insets in the cabinet. So no, the KLH 6 woofers will not work. The woofers on my optimus 1's had hardened cloth surrounds so they had very limited bass. The...

    Mach one, Nova 8B, Optimus? Which is best

    We recently had a young couple in our home for a bbq and I put on The Rippington's. The were blown away by my 8b's. They didn't know that kind of sound existed. Seriously. At first they couldn't figure out where the sound was coming from because the 8b's veneer color is very close to the cabinet...

    KLH tweeters. Which are the same as the model 5?

    Interesting that no one has asked the question "Are you sure the tweeter is dead?" Did you actually check it with an ohm meter? Tweets on these old KLH's are notorious for going dead due to aged crossover capacitors that have gone out of spec. Dig into other threads here on AK. Lots of info...

    Upgrade or Downgrade?

    Just speaking to the Marantz 2220b vs the SA-720. I am inclined to the think that the 2220b would not be an upgrade since it is only a 20 watt per channel RMS rating. If memory serves me correctly the 720 is a 40 watt per channel unit. A greater consideration would be the age of the 2220b...

    KLH Twenty Threes more help needed.

    I've had numerous KLH's including 6's, 23's, and 5's. Nearly all of them had the sound you described initially. Recap and applying fresh dope to the surrounds should make all the difference unless there's a bad tweet. +1 on the 180 degree turn of the woofer. FYI...the 23's are my personal...

    What to do????? Sansui G7500 for 2 D9 Vagas

    You'd need to find out what work has been done on the Sansui. If it has been restored then it's probably a good trade both ways. If not, it could become regrettable quite quickly. 40 year old electronics are working on borrowed time and then finding a local shop willing to do repair on vintage...

    Powered Subwoofer Stays In Protection At Power Up

    I recently purchased a Phase Tech Octave 10 powered sub woofer on marketplace. Upon power up it stays in protection and has a steady hum until an audio signal is presented. Once an audio signal is presented it goes out of protection and sounds great. I called Phase Tech and this unit is quite...

    vintage gear redux

    My experience with vintage vs modern gear basically is that most modern gear (but not all) sounds better with a sub woofer in the mix. Vintage receivers such as the SX-750 which was a middle of the pack receiver have far larger power supplies than modern gear of today, thus better low frequency...

    Can someone Identify this enclosure?

    I once had a Hardon karman 330b receiver that was in a similar sized cabinet. The wood cabinet was optional on that model. There's no way of knowing for certain what your cabinet may have been used with but it certainly could have been a 330a or 330b.

    Swapping my Receivers for Integrated

    The word you're looking for on the A-10 I think is "neutral". The A-5 signature is very much the same as well. I regret letting mine go. Now that the word is out they require some extra change. They seem to be bullet proof and don't require a lot of bench time either.

    Swapping my Receivers for Integrated

    I've had kenwood, yamaha,& pioneer integrateds as well as the Onkyo A-10 and A-5. The A-10 wins hands down sonically and has great looks as well. A 45lb beast for sure!

    A Kabuki diamond in the rough, or am I losing my hearing?

    Hey you can't beat free! Would you be willing to remove the woofer and take a pic or two of the innards and the crossover? Probably not much going on but hey, you never know. I picked up some Sony towers at a garage sale for 10 bucks a few months back for a quick flip. They sounded way better...

    Yahama RX-V2600

    The 2600 is a substantial unit. Just make sure it's vented well (nothing sitting on top) and it should be fine. I had an RX-V2092 that was a 50lb beast. It was capable of running 4 sets of speakers + center and did quite well down to a 2 ohm load. It definitely ran warm when pushing 2 ohms...

    Optimal Spotify listening via iphone

    Make sure you're connecting to an aux or tape input, not the phono! I made the mistake one time of connecting to the phono inputs...big no no...but then actually did work well when I brought the iphone vol way down. I've connected MP3 players, Iphone's etc to 750's, 850's, 990's etc without...

    Replacement Speakers for Realistic Optimus 5B's

    Common issue with Nova 8b's and Optimus 5b's. Replacements come up fairly often on the auction site. Keep with OEM if possible. Keep in mind that while the mids and tweet look identical they are not. I believe the mids are 8 ohm and the tweets are 4 ohm. I've got a set of Nova 8b's but its been...

    Pioneer SX-750 custom cabinet refresh

    I see occasionally new built bonnets for the bigger Pioneer units SX-850 and up and sometimes for the 750 on the auction site. Go into the advanced settings on a listing and select sold. You'll then be able to see the listings of that item that have sold in the last few weeks and sometimes...

    easiest way of sharing recordings with family?

    Since they are well into their 60's I would guess that they all have CD players still, if not 8 track and cassettes too. :biggrin: Send them emails or actually pick up the phone (yikes :crazy:) and call them to see what works for them. Betcha CD's is going to be what they want.
